1Co 6:18 “Flee fornication. Every sin that a man commits is outside the body; but he who commits fornication sins against his own body.”
The word “fornication” comes from the Greek “porneia”, from where “porno” also is derived, and it means harlotry, whoredom, sexual immorality.
There are 32 verses in the Bible that talk about fornication. At first, it defined the actions of a man and a woman having intercourse outside the covenant of marriage.
God created marriage between a man and a woman in the Garden of Eden. He created them, male and female, and gave them the marriage covenant to be together “’till death did them part”.
After man fell into sin, his marriage blissfulness was broken. Man became a depraved creature, full of wickedness and rebellion against God. He forgot the God who created him and followed after his new master, the devil.
In this condition, the human heart sought new inventions. Sinful and wicked inventions. Man was always seeking something new and different, but far from God. Man broke his marriage covenant and corrupted himself by commiting adultery, and going after strange flesh (homosexuality).
We read in Romans 1:21-32
“Because that, when they knew God, they glorified him not as God, neither were thankful; but became vain in their imaginations, and their foolish heart was darkened…Professing themselves to be wise, they became fools…
Wherefore God also gave them up to uncleanness through the lusts of their own hearts, to dishonour their own bodies between themselves: … Who changed the truth of God into a lie, and worshipped and served the creature more than the Creator, who is blessed for ever. Amen.
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; men with men working that which is unseemly, and receiving in themselves that recompence of their error which was meet.”
Notice that God says twice, “God gave them up” in this passage. This is the most terrible thing that can happen to men, in addition to death.
That’s the reason why Isaiah prophesied that “hell has enlarged herself, and opened her mouth without measure: and their (men’s) glory, and their multitude, and their pomp, and he that rejoices, shall descend into it.” (Isa. 5:14)
