It is such a fundamental wrong, that when it comes to voting, a candidate's stance on other issues is irrelevant if he or she favors abortion. A vote is not a passive act. By voting for a particular candidate, the voter participates in promoting the agenda of the candidate in an intentional action. When a candidate for a government office promotes the sin of abortion, God's people must take action to oppose this sin of abortion and defend those affected by it. Abortion is an atrocity that takes the lives of over 3,000 children every day.
Abortion is an atrocity that wounds women and destroys relationships.
To be in favor of such an atrocity is symptomatic of a certain moral view of life that has broader implications as well. But the abortion issue is of transcendent importance. Abortion is a spiritual issue. Abortion is a sin. We cannot vote for sin.
