I don't think that's exactly how it works. Sin is sin. Whether it's homosexuality or stealing or lying. We have all sinned in one way or another. The important factor is did he repent of those sins? Yes Christ did die for each one of our sins but unless we accept the fact that he did and then repent of our sinful life and then change who we were before then I'm afraid Mr. Bowie isn't celebrating in heaven. It's a harsh thing to say, but that's the truth. We are given free will to choose what we will do. I do not know his heart, nor will I begin to speculate. It is not my place to judge. But for his own sake, and for the sake of those who love and admire him, I pray that he did accept Jesus as his personal savior.
