Christians are often labeled as picking and choosing their definition of sin because they are often seen decrying homosexuals by using verses in Leviticus that speak of it as a sin, but ignoring other claims from the same book about wearing mixed fabrics, not eating animal fat. Those that point those out do not understand the full message of the Bible. Those who are truly willing to investigate this (instead of just accusing) would quickly realize that the majority of the laws written down in the Old Testament were customs and traditions for the Jewish people.
Old Testament literally means “old covenant”. The new covenant is when Jesus came to (not abolish) but fulfill the old covenant. Everything in the Old Testament is leading to the time of Jesus. His presence and atonement changes everything! The messianic purpose of Jesus is to move Jews to Christians. Jesus summed up the law for Christians – love the Lord your God and your neighbor as yourself.
So now why is homosexuality still a sin when others are not? The answer is simple – because it is referenced in the New Testament. Keep in mind there is no ancient word for homosexuality, as that wording is modern.
Romans 1: 26-27 – “Because of this, God game them over to shameful lusts. Even their women exchanged natural sexual relation for unnatural ones. In the same way the men also abandoned natural relations with women and were inflamed with lust for one another. Men committed shameful acts with other men, and received in themselves the due penalty for their error.”
1 Corinthians 6: 9-10 – “Neither the sexually immoral nor idolaters nor adulterers nor men who have sex with men nor thieves … will inherit the kingdom of God.”
Another helpful reminder is when Jesus himself defined marriage as between a man and a woman in Matthew 19. Truly homosexuality is still viewed as a sin in the covenant Jesus created until He comes again.
There are four ways for Christians to react to gays, or anyone else committing sin:
1. All love, no truth (tolerance) – Christian churches today that are embracing gays openly.
2. All truth, no love (judgment) – Churches such as Westboro Baptist.
3. Denial – doesn’t affect my church.
4. Some love, some truth – Love the sinner, hate the sin.
Approach 4 is the very definition of grace with salt found in Colossians 4:6 – “Let your conversation be always full of grace, seasoned with salt, so that you may know how to answer everyone.”
