Or 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 effeminate, nor homosexuals, nor thieves, nor the covetous, nor drunkards, nor revilers, nor swindlers, will inherit the kingdom of God. 1 Corinthians 9-10
The Bible does state that homosexuality is a sin, however so is divorce and sex before marriage as well as lying, stealing and gossiping. All these are sins that require repentance and all these are sins that will be forgiven in baptism.
