The TRUE struggle behind the issue is a spiritual one - they (homosexuals) are caught in the bondage of sin, and unless and untill they admit that they are sinning, they cannot escape that bondage.
"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 homosexuals, nor sodomites,nor thieves, nor covetous, nor drunkards, nor revilers, nor extortioners will inherit the kingdom of God.
And such were some of you. But you were washed, but you were sanctified, but you were justified in the name of the Lord Jesus and by the Spirit of our God."
1 Corinthians 6:9-11
Agreed.
The author's point is that God is powerful enought to break those chains of bondage, as the author points out that God has done in his life! So yes, they must admit that they are sinning, but then what? God is the one that frees them, and that's the point!
