Please explain: "God loves the sinner but hates the sin." Is not the homosexual act and the person one and the same?


They are not the same because sin cannot change from being wrong, but a person can change from doing wrong. See: Should we separate a man from his deeds, hating his sins while loving the sinner?

One of the current myths about homosexuality is that it is ingrained in a person and cannot be changed. This is shown false when Paul pointed out that there were former homosexuals in Corinth. "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" (I Corinthians 6:9-11).
