It's right there in the bible... god does not mince words...
If a man has sexual intercourse with a male as one has sexual intercourse with a woman, the two of them have committed an abomination. They must be put to death; their blood guilt is on themselves.
Pretty straight-forward, right?
"They must be put to death"... you must murder them... will you do it?
That is during the law. We are now under grace. Jesus came to die for the sins of all humanity and it only takes belief in Him and His work on the cross and turning away from sin. Those who will not believe will be under judgemet and will perish. It is true the old testament Bible said it but we are now not living under the law but under grace by believing in Jesus. Secondly, God will not tell anyone to kill the abominables their time has not yet come.
