Homosexual sin is a grievous and heinous sin. While it is indeed true that all sexual immorality is sin—adultery, fornication, pornography—homosexual sin is different. It is a more heinous and grievous sin because, as the Word of God makes clear, homosexual sin is contrary to nature (Rom. 1:26). Homosexual sin strikes against God's created order in every way and mocks God's design for procreation, thus making homosexuality logically self-defeating. Those who suggest the Bible is not clear about homosexual sin have never read the Bible or have not been given the ears to hear what the Bible plainly teaches.
The Bible is clear, so we must be clear. We cannot and must not waver in the face of seemingly overwhelming opposition. Although the world is changing, the Word of God is not. We must stand our ground on the unchanging Word of God in the midst of an ever-changing culture. For even if the whole world says homosexuality is acceptable, we must stand our ground on the authority of God's Word and insist that it is in fact unacceptable and unconscionable. We must speak the truth even if it means persecution and imprisonment. We must insist that homosexual sin is wrong, and like all sins, sexual or otherwise, it is deserving of God's righteous wrath and condemnation.
Make no mistake, this is not hate speech; it is love speech. We speak of the sinfulness of homosexual sin, sexual sin, and all sin not out of hate, but out of love. In fact, the most hateful thing we could do is not call sin what God calls sin. That would certainly be the easier path for us, but it is not the path of truth that leads to forgiveness and freedom. We love homosexuals just as we love adulterers and all sinners, which is precisely why we must speak the truth in love to them, just as we need the truth spoken in love to us about our own sins. The Bible calls us to be righteously vexed by sin and to hate sin—our sin and the sins of the world. The Bible also calls us to love sinners and to pray that they would repent of their sins and trust Jesus Christ, who is the Savior of repentant sinners. If only more Christians demonstrated Christian love as they should by praying for the sexually immoral of this world, by calling sin what God calls sin, and by proclaiming the gospel of Jesus Christ to the end that the sexually immoral might know their desperate need to repent and that, by the grace of God, they might cling to Christ and His righteousness. Then homosexuals might know how much we Christians love them. For we cannot love without speaking the truth, and we must not speak the truth without love. We must have compassion and courage as we live coram Deo, before the face of God, proclaiming His truth and His gospel to our homosexual neighbors, sexually immoral neighbors, and unrepentant, unbelieving neighbors, just as we preach the gospel to ourselves.
