Thou shalt not lie with mankind, as with womankind: it is abomination. Leviticus 18:22
Why is homosexuality an abomination before the Lord?
In the day that God created man, in the likeness of God made he him; Male and female created he them; and blessed them, and called their name Adam, in the day when they were created. Genesis 5:2
Jesus in Matthew 19:4 "Have you not read that he who created them from the beginning made them male and female, and said, Therefore a man shall leave his father and his mother and hold fast to his wife, and the two shall become one flesh’
"Therefore a man shall leave his father and mother and hold fast to his wife, and the two shall become one flesh.” This mystery is profound, and I am saying that it refers to Christ and the church. Ephesians 5:31-32
alter (something) from its original course, meaning, or state to a distortion or corruption of what was first intended.
Satan cannot create, and so has nothing original to offer man. Therefore he perverts the good that God has made into something evil.
For example; there can be no cursing if there is no speech, no idolatry if there is no worship, no killing if there is no life, no adultery if there is no marriage, and no homosexuality if there is no sexuality. Satan has no remorse and no shame. He will use all his power to pervert the image of God through man who was created to glorify that image.
For the wrath of God is revealed from heaven against all ungodliness and unrighteousness of men...who changed the truth of God into a lie...for this cause God gave them up unto vile affections: for even their women did change the natural use into that which is against nature: And likewise also the men, leaving the natural use of the woman, burned in their lust one toward another... Romans 1
Know ye not that your bodies are the members of Christ? shall I then take the members of Christ, and make them the members of an harlot? God forbid. What? know ye not that he which is joined to an harlot is one body? for two, saith he, shall be one flesh. But he that is joined unto the Lord is one spirit. Flee fornication. Every sin that a man doeth is without the body; but he that committeth fornication sinneth against his own body. What? know ye not that your body is the temple of the Holy Ghost which is in you, which ye have of God, and ye are not your own? 1Corinthians 6:15-19
Know ye not that ye are the temple of God, and that the Spirit of God dwelleth in you? If any man defile the temple of God, him shall God destroy; for the temple of God is holy, which temple ye are. 1 Corinthians 3:16-17
God created us in His image, and has a purpose for our lives.That makes every one of us intrinsically valuable and immeasurably meaningful in His eyes. He created us as a temple of His Trinity, for the Holy Spirit to dwell in us. He defined marriage as the symbolic relationship between Christ and the church.
To pervert and corrupt that purpose from what God intended it to be, is indeed an abomination to The Lord.
Do you not know that the unrighteous will not inherit the kingdom of God? Do not be deceived. Neither fornicators, nor idolaters, nor adulterers, nor homosexuals, nor sodomites, nor thieves, nor covetous, nor drunkards, nor revilers, nor extortioners will inherit the kingdom of God. 1 Corinthians 6:9-10
