Question: What is your advice and opinion regarding Christians being active in the anti-abortion movement, i.e., picketing, demonstrations, etc.? Or do you recommend a different approach to this issue?
Response: Abortion should be opposed in preaching, writing, and speaking by Christians. Even non-Christians ought to oppose it, and many do, for the purely moral reasons that have been written by God in every person's conscience (Rom:2:14-16). How could anyone ever have approved of partial-birth abortion, for example? The baby is turned around in the womb so that it comes out feet first, and, with a small part of the crown of the head technically inside the birth canal, an insertion is made and the brains sucked out. A few more inches and the courts would call it murder. And not to call it murder then—or earlier in the womb—is a wickedness for which America and this world will receive God's just punishment.
We are not, however, in favor of joining with Catholics, Mormons, atheists, humanists, or any other non-Christians in protest marches or other activism, whether against abortion or for or against anything else. We are not to be unequally yoked together with unbelievers in any endeavor.
Such alliances necessarily silence a real Christian's witness for Christ. Why? How can I witness to the Mormon on my right side and the Catholic on my left and the atheist just behind me, when to do so would offend them? Being true to Christ and His Word would break up the coalition I must join to engage in such activities.
We ought to stand against abortion in every biblical and effective way that we can as true believers without joining unbelievers in any "action" they wish to take. But our primary role is to preach the gospel and make disciples for our Lord—not to become absorbed in trying to make a godless world behave like Christians.
