What I have to say is to people who claim to be Christians.
Jesus spoke out against sexual immorality.
18 But the things that come out of the mouth come from the heart, and these make a man unclean. 19 For out of the heart come evil thoughts, murder, adultery, sexual immorality, theft, false testimony, slander. 20 These are what make a man unclean; but eating with unwashed hands does not make him unclean.
20 He went on: “What comes out of a man is what makes him unclean. 21 For from within, out of men’s hearts, come evil thoughts, sexual immorality, theft, murder, adultery, 22 greed, malice, deceit, lewdness, envy, slander, arrogance and folly. 23 All these evils come from inside and make a man unclean.
We have to realize that sexual immorality is a category of sin that includes all sexual sin.
1 Corinthians 5:1
It is actually reported that there is sexual immorality among you, and of a kind that does not occur even among pagans: A man has his father’s wife.
Paul had to deal with one specific instance of sexual immorality: a man having sex with the wife of his father. This is identified as a sin in the Old Testament, specifically Leviticus 18:8, Leviticus 20:11, Deuteronomy 22:30, and Deuteronomy 27:20. Paul did not further address specific examples of sexual immorality in this passage. However, it is clear that it was a category of sin that dealt with sex that God had prohibited.
Christ said the entire category of sin known as sexual immorality was evil.
Now, sexual immorality would refer to what God had defined as wrong already by the time of when Christ said this; this would come from the Old Testament. As Christians today, we use both the Old and New Testaments to see Who God is, what God has done, how God feels about issues in life, and what He expects of and for us.
The word translated as sexual immorality is Porneia. This word means
1. illicit sexual intercourse
A. adultery, fornication, homosexuality, lesbianism, intercourse with animals etc.
B. sexual intercourse with close relatives; Lev. 18
C. sexual intercourse with a divorced man or woman; Mk. 10:11
Romans 1 says even the desire of a man for a man or a woman for a woman is sin. The act of sex between two people of the same gender is also sin.
The term translated in Romans 1 as ‘lust’ is epiqumia in Greek. It means desire, craving, longing, desire for what is forbidden, lust.
It is even the mere desire for same gender sex that is wrong in God’s eyes.
Paul said we must turn away from wickedness if we confess Christ as Lord:
2 Timothy 2:19
Nevertheless, God’s solid foundation stands firm, sealed with this inscription: “The Lord knows those who are his,” and, “Everyone who confesses the name of the Lord must turn away from wickedness.
Paul also said God will punish men for sin.
1 Thes 4:3-8
3 It is God’s will that you should be sanctified: that you should avoid sexual immorality; 4 that each of you should learn to control his own body in a way that is holy and honorable, 5 not in passionate lust like the heathen, who do not know God; 6 and that in this matter no one should wrong his brother or take advantage of him. The Lord will punish men for all such sins, as we have already told you and warned you. 7 For God did not call us to be impure, but to live a holy life. 8 Therefore, he who rejects this instruction does not reject man but God, who gives you his Holy Spirit.
It does not matter how you feel about it. It does not matter how you justify it. God said if you do not change and turn to God, then you are not saved. If you claim you have repented and turned to God, then you need to live like it.
