There is no sin but the sin we create for ourselves. Each man defines his sin by his acts in the world and not by his lifestyle.
I know this for sure being a man who has received numerous visitations from Jesus Christ.
I have been a Christian for 1/3 of my life, before that I was an agnostic. What changed me was the many visitations I received from Jesus. He performed numerous miracles to save me from a suicide, two battles with cancer and a major heart attack. Finally he asked that I write a book telling the world what he taught me. The books is titled "Lead Us Not Into Temptation" avail online thru Amazon, Borders and Barnes & Noble, by Raymond Arroyo, for those interested.
