You may have heard the saying, “Ideas have consequences.” That’s actually a famous book title from a political conservative just after World War II. And it’s true. Ideas do have consequences. And bad ideas have bad consequences. This is just as true in culture and politics as anywhere else. If you look at the cultural and political evils that surround us today (abortion, same-sex “marriage,” Obamacare, gun confiscation laws, judicial tyranny), at their source are bad ideas. It’s hard to get rid of the bad politics without getting rid of the bad ideas that feed them and give them sustenance.
But the bad ideas I want to address right now aren’t so much bad ideas in the culture and in politics. I want to talk about bad ideas in the church that allow these bad ideas in the culture to flourish.
Many of us are conflicted today. We’re political conservatives. We believe in limited government, the dignity of human life, the traditional family. We believe in what’s called “civil society”: the church and family and other “private” institutions are buffers that protect the individual from, and are competitors to, the state. We believe in Christian virtues: love, faith, hope, honesty, sacrifice, hard work, personal responsibility, We believe that God’s moral law binds everyone, Christian and non-Christian.
But we’re more: many of us are activists. Our country is dangerously adrift — a monster federal government, erosion of states’ rights, abortion, pornography, gay “marriage,” euthanasia, Obamacare, increased gun control laws — and we are committed to doing something about it. We embrace conservative ideas, but those ideas lead us to action: perhaps staging get-out-the-vote programs, trying to elect Christian and conservative candidates, influencing legislation for conservative principles. We’re aggressive.
This is just where a conflict rises. As Christians, we’re church people. We must believe in and belong to the church. But many of our churches are not comfortable with our conservative political action as Christians. Some alleged Bible-believing churches aren’t even politically conservative. Even churches that are politically conservative look down on political activism — what we’re committing part of our life to. They practice what I’d like to call “separation of church and politics.”
The pastor may mention conservative issues, but political action isn’t seen as part of a Christian calling. Maybe it isn’t even Christian at all. Maybe it’s just like picking up groceries or attending the football game. It’s OK, but it’s not especially Christian. It’s just something we choose to do. And we’re tempted to think: “I can’t be a good Christian and an active conservative” or, “I must leave my politics at the church door, or leave my Christianity inside the church.” This is the conflict that we feel.
I’d like persuade you today: there is no actual conflict. You can be a political activist and good Christian at the same time. I’ll be even bolder: you cannot be a good Christian unless you’re zealously conservative.
Today I’ll refute three popular but bad ideas in the church. You can be more confident, not just as conservatives … but as politically active Christian conservatives.
By pietism I don’t mean piety. What is piety? It’s “the quality of being reverent.” It’s worshiping the Triune God, loving, honoring him, trusting in his Son Jesus Christ. It’s a heart right with, and riveted to, God. We need more piety.
In addition, by pietism, I don’t mean the 17th – 18th century movement reacting against the cold, hard, sterile orthodoxy of scholastic Protestantism. That was a good movement, and it restored an emphasis on warm piety and love for Jesus Christ.
I mean pietism in a more recent, limited sense. The distinctive of this pietism is that it limits the Christian life to private devotion or the church (Bible reading, personal evangelism, end times conferences, “quiet time,” personal taboos). It’s mostly vertical religion.
Pietistic thinking goes like this: “God doesn’t care about politics (or education, art, medicine, technology, economics, music, movies). He cares about my private relation to him.”
Pietistic churches think this way: “You’ve done your Christian duty when you pray, attend church, read your Bible, and volunteer for VBS.”
Pietistic pastors preach: “Political action distracts and detracts from true Christianity. Real Christianity in the church is about a bigger gymnasium, a larger AWANA program, and more beautiful robes.”
Pietism reduces Christianity to a “personal worship hobby.”
The big problem with pietism is that it undercuts Jesus Christ’s Lordship. We all know the simple saying: Jesus Is Lord. Actually, did you know that this was the earliest creed of the Christian church? Long before the Apostles Creed, there was this simple creed: Jesus is Lord, and Lord = Master.
Question: What is Jesus Lord of? I think we’d answer, he’s Lord of everything. Next question: Is politics part of everything? Yes. Then by simple logic, Jesus is Lord of politics, and this is just what the Bible teaches.
The Lord instructed us to pray: “Your kingdom come, your will be done, on earth as it is in heaven” (Mt. 6:10). On earth, not just in the family and church — but everywhere.
Another question: how is Jesus’ will done in heaven? It’s done perfectly. The angels and saints obey him without sin. That’s just what we need to pray for this earth. And this must mean everything, not just our private time and Sunday worship, not just the house and the church house but also the state house and the schoolhouse and the White House.
And then we read Jesus’ parting words to his disciples in Matthew 28:18, the so-called Great Commission: “All authority in heaven and on earth has been given to me.” And then he commands his followers to disciple the nations, not just individuals, but nations. He means to bring all nations, political units, under his authority.
God the Father gave Jesus the authority to bring all nations under his rule, and he charged us to preach the Gospel and baptize and instruct the nations to do just that.
Therefore, pietism dilutes Jesus’ Lordship. It wants to say to Jesus: “You can be Lord here, but not there. You can be Lord of the church house, but not the state house.” This is a denial of the full Lordship of Jesus Christ.
Pietism leads to strange bedfellows. Secularists say, “Christianity should stay private.” Pietists respond, “We agree.” Secularists say, “Christians should stay out of politics.” Pietists respond, “We agree.” Secularists say, “God’s Word has nothing to say to our society.” Pietists respond, “We agree.” Secularists say, “Unbelievers should be calling all of the shots in society and culture.” Pietists respond, “We agree.” Secularists say, “Christianity is a ‘private worship hobby.’” Pietists respond, “We agree.”
I think it’s about time we Christians quit agreeing with the secularists.
Pietism surrenders culture to Satan: it’s a sub-Christian idea, and it’s dangerous.
Apocalypticism is end-is-near thinking that inspires cultural sit-on-your-duff Christianity, except for pietistic soul-saving: “The world is getting worse and worse; so it’s a waste of time to change things.” As D. L. Moody once said, “I look upon this world as a wrecked vessel…. God has given me a lifeboat and said to me, ‘Moody, save all you can.” It’s the idea that since the Bible teaches that the world must get worse and worse (the Bible doesn’t actually teach this), it’s futile to try to change things. God has predestined evil to triumph, so why stand in his way?
Now, there are many different views of eschatology (views of the future). Sincere, Bible-believing people hold different eschatologies. We can agree to disagree. However, I don’t care what your eschatology is, apocalypticism is wrong. We read in Acts 1:6–8 … “So when [the disciples] had come together, they asked [Jesus], ‘Lord, will you at this time restore the kingdom to Israel?’ He said to them, ‘It is not for you to know times or seasons that the Father has fixed by his own authority. But you will receive power when the Holy Spirit has come upon you, and you will be my witnesses in Jerusalem and in all Judea and Samaria, and to the end of the earth.’”
Jesus is saying, “You don’t need to know the ‘end times.’ You need to take the message of salvation of my Gospel Lordship (that includes politics) everywhere.” 
Similarly, we read in Luke 19:13 that Jesus in a parable said to his followers: “‘Engage in business until I come.’” In short, be busy in my kingdom work. Don’t sit around and wait for the Second Coming or “rapture.”
Twenty years ago in Ohio I was preaching to pastors on this topic. I was lamenting abortion, pornography, homosexuality, and socialism. I was exhorting these pastors in their calling to stand up and oppose these evils.
Afterward a pastor accosted me and said: “Yes, all the abortion, porn, homosexuality, and socialism are bad, but really in the end they’re good, since they mean Jesus coming soon.”
If that idea sounds perverted, it’s because it is.
The churches obsessed with “end times” (conferences, books) while Planned Parenthood crushes and sells baby parts, and the U.S. Supreme Court allows sodomites to marry, are dangerously misguided. They’re selling us into cultural slavery.
Apocalypticism, like pietism, is an evil idea.
Recently a leader in the very conservative Southern Baptist Convention declared, “We’ve lost culture wars.” His view is: Let’s just witness; we must be careful about pushing for a Christian America, turning people off. We need to change our strategy.
And churches line up to retreat — they stay out of politics, quit praying outside abortion clinics, pull back from pressing for godly candidates and legislation.
Christian leaders say: “We live in a time when the church is in the wilderness, in exile. Let’s hide out from the Devil. Admit it. We’ve lost. Let’s regroup and wait for a more culturally hospitable time.”
This is pure poppycock. Canaan was devilishly depraved when God told the Jews to take it for his name (Gen. 15:16).
The Roman Empire was a moral sewer when our Lord gave his world-conquering commission to his disciples. He didn’t say, “There’s no way we can win this thing, fellas, so let’s retreat until we can plan a counterattack.” The early Christians took the Gospel to the known world, and in less than 300 years the Roman Empire was forced to become Christian. Why? Because our forebears refused to retreat during culturally depraved times like ours.
Some Christians seem to believe that if they just avoid confronting the Devil in the culture, he’ll leave them alone in their churches and families. This is a dangerous illusion. You might hide out from the Devil, but the Devil won’t hide out from you. If you retreat from him in public and politics, he’ll hunt you down in the privacy of your own home.
Then behind retreatism is the additional idea that world belongs to Devil: “This world is not my home, I’m just a’passin’ through,” so goes an old gospel song. “Why should we stand for truth in our world since it doesn’t belong to us or Jesus, but to the Devil?”
Have you ever read that in Bible? No.
You did read in 1 Corinthians 10:26, “For ‘the earth is the Lord’s, and the fullness thereof.’”
This is God’s world; he created it; he sustains it. He designed it to operate by his truth.
God allows man freedom, so there’s a great battle between good and evil. But if we give up the battle for this world, we are traitors to the King; it’s not our world, it’s his world.
Retreatism is treason; it surrenders God’s world to his enemies.
Pietism, apocalypticism, retreatism — these are bad church ideas that produce bad political consequences. And if you want to know one reason the culture is so depraved today, it’s because the church has bought stock in these ideas, and this creates the conflict in the minds of hearts of politically active Christian conservatives.
But you should not feel a conflict, because there is no conflict between true Christianity and conservative political activism. In fact, if we do not stand for what we today call basic conservative principles, we are not standing for biblical Christianity, because those principles reflect biblical truth.
The call for retreat from political battle for Christ the King is a sub-Christian message.
In the early 40’s amid euphoria of the rescue of thousands of British troops from the German army at Dunkirk, Prime Minister Winston Churchill warned: “Wars are not won by evacuations…. We shall fight on the beaches, we shall fight on the landing grounds, we shall fight in the fields and in the streets, we shall fight in the hills; we shall never surrender.”
Wars are not won by evacuations. Wars are won by soldiers who stand and fight.
That is our rallying cry for the King of Kings and Lord of Lords. And we can expect nothing short of complete victory — the unconditional surrender of Satan and his hosts by the power of Jesus Christ.
