From a sermon John Piper preached in 1982 called “Flesh Tank and Peashooter Regulations”:
Legalism is a more dangerous disease than alcoholism because it doesn’t look like one. Alcoholism makes men fail; legalism helps them succeed in the world. Alcoholism makes men depend on the bottle; legalism makes them self-sufficient, depending on no one. Alcoholism destroys moral resolve; legalism gives it strength. Alcoholics don’t feel welcome in church; legalists love to hear their morality extolled in church. Therefore, what we need in this church is not front-end regulations to try to keep ourselves pure. We need to preach and pray and believe that "Neither circumcision nor uncircumcision, neither teetotalism nor social drinking, neither legalism nor alcoholism is of any avail with God, but only a new creation (a new heart)" (Galatians 6:15; 5:6). The enemy is sending against us every day the Sherman tank of the flesh with its cannons of self-reliance and self-sufficiency. If we try to defend ourselves or our church with peashooter regulations, we will be defeated, even in our apparent success. The only defense is to "be rooted and built up in Christ and established in faith" (Colossians 2:6); "Strengthened with all power according to his glorious might for all endurance and patience with joy" (Colossians 1:11); "holding fast to the head from whom the whole body, nourished and knit together, . . . grows with a growth that is from God" (Colossians 2:19). From God! From God! And not from ourselves.
