The Bible says a great deal about homosexuality and other forms of sexual sin. Here are just a few of the references that you will find during a thorough search of the Scriptures.

Suppressing the Truth of God with a Lie

Romans 1 is unmistakable in its stand against of homosexual behavior. Along with the other sins mentioned in this passage, homosexual sin is a consequence of man's rejection of God.

For there is a revelation of the wrath of God from heaven against all the wrongdoing and evil thoughts of men who keep down what is true by wrongdoing;
Because the knowledge of God may be seen in them, God having made it clear to them.
For from the first making of the world, those things of God which the eye is unable to see, that is, his eternal power and existence, are fully made clear, he having given the knowledge of them through the things which he has made, so that men have no reason for wrongdoing:
Because, having the knowledge of God, they did not give glory to God as God, and did not give praise, but their minds were full of foolish things, and their hearts, being without sense, were made dark.
Seeming to be wise, they were in fact foolish,
And by them the glory of the eternal God was changed and made into the image of man who is not eternal, and of birds and beasts and things which go on the earth.
For this reason God gave them up to the evil desires of their hearts, working shame in their bodies with one another:
Because by them the true word of God was changed into that which is false, and they gave worship and honour to the thing which is made, and not to him who made it, to whom be blessing for ever. So be it.
For this reason God gave them up to evil passions, and their women were changing the natural use into one which is unnatural:
And in the same way the men gave up the natural use of the woman and were burning in their desire for one another, men doing shame with men, and getting in their bodies the right reward of their evil-doing.
And because they had not the mind to keep God in their knowledge, God gave them up to an evil mind, to do those things which are not right;
Being full of all wrongdoing, evil, desire for the goods of others, hate, envy, putting to death, fighting, deceit, cruel ways, evil talk, and false statements about others;
God-haters, full of pride, without respect, full of loud talk, given to evil inventions, not honouring father or mother,
Without knowledge, not true to their undertakings, unkind, having no mercy:
Who, though they have knowledge of the law of God, that the fate of those who do these things is death, not only go on doing these things themselves, but give approval to those who do them. Romans 1:18-32

Go and Sin No More

In this account of a woman's adulterous encounter with another man, Jesus forgives sin and commands repentance from sin.

And early in the morning [Jesus] came again into the Temple and all the people came to him and he was seated teaching them.
Now the scribes and Pharisees came, with a woman who had been taken in the act of sinning against the married relation;
And putting her forward, they said to him, Master, this woman has been taken in the very act of sinning against the married relation.
Now in the law Moses gave directions that such women were to be stoned; what do you say about it?
They said this, testing him, so that they might have something against him. But Jesus, with his head bent down, made letters on the floor with his finger.
But when they went on with their questions, he got up and said to them, Let him among you who is without sin be the first to send a stone at her.
And again, with bent head, he made letters on the floor.
And when his words came to their ears, they went out one by one, starting with the oldest even to the last, because they were conscious of what was in their hearts: and Jesus was there by himself with the woman before him.
Then Jesus got up, and seeing nobody but the woman, he said to her, Where are the men who said things against you? did no one give a decision against you?
And she said, No man, Lord. And Jesus said, And I do not give a decision against you: go, and never do wrong again. John 8:2-11

And Such Were Some Of You

The Bible clearly states that all have sinned and fall short of the glory of God (Romans 3:23). Jesus stands ready to forgive all sin and to transform us from our sinful ways into His righteousness through the power of the Holy Spirit.

Have you not knowledge that evil-doers will have no part in the kingdom of God? Have no false ideas about this: no one who goes after the desires of the flesh, or gives worship to images, or is untrue when married, or is less than a man, or makes a wrong use of men,
Or is a thief, or the worse for drink, or makes use of strong language, or takes by force what is not his, will have any part in the kingdom of God.
And such were some of you; but you have been washed, you have been made holy, you have been given righteousness in the name of the Lord Jesus Christ and in the Spirit of our God. 1st Corinthians 6:9-11
