The biblical truth about homosexual marriage.
There is a misconception concerning homosexuality and the Bible. Many liberals attempt to infer that because Christ did not mention the sin in no longer exist in the New Testament. They fail to mention that the apostles that were appointed by Christ do in fact mention the sin and condemn it. The apostles also make it very clear that those who practice it will never enter heaven.
New Testament
Rom 1:26
For this reason God gave them over to degrading passions ; for their women exchanged the natural function for that which is unnatural ,
1 Corinthians 6:9
Do you not know that the unjust will not inherit God's kingdom? Do not be deceived: no sexually immoral people, idolaters, adulterers, male prostitutes, homosexuals,
1 Timothy 1:10
for the sexually immoral and homosexuals, for kidnappers, liars, perjurers, and for whatever else is contrary to the sound teaching 11 based on the glorious gospel of the blessed God that was entrusted to me.
There are a ton of Scriptures on this matter bu I'll just give you a few.
Old Testament
Leviticus 20:13
If a man also lie with mankind, as he lieth with a woman, both of them have committed an abomination: they shall surely be put to death ; their blood shall be upon them.
None of this in any way means that a homosexual who does not practice homosexuality cannot make it into heaven. Homosexuality is on the same plane as an adulterer or adulterous.
