He forgave all sin, not just adultery and homosexuality. But sin is still sin--when he healed people, what did he say? Go and sin no more. If a person is in open rebellion to G-d (as this person obviously is), then it is very difficult for him to hear and recognize the voice of G-d.) I recommend for those of you (meaning all of us) that struggle with the connection of Jewish concepts and the relation of the Law with Christians that you read "Galatians" by Avi ben Mordechai. I don't want to get in a theological debate about Law vs. Grace, but it is good that we all search for the Truth.
I concur, with the understanding that all sin is offensive to Our Heavenly Father; IOW there is no degree of sin. Therefore the sin of a homosexual act is just as bad as fornication (guilty), lying (guilty), adultery (guilty), dishonoring parents (guilty), failing to keep a holy Sabbath (guilty), (stealing) guilty, drunkedness (guilty), lust (guilty), coveting a neighbor's wife (guilty), etc., etc.
