I have been gay my entire life. Being raised in a Christian home, I have wrestled with this for a very long time, trying to reconcile my homosexuality with the truths of my faith.
One thing I know is that God loves me and wants the best for me. All He requires of me is to be faithful and seek His perfect will for every area of my life. I now realize that though I am gay, I will keep myself undefiled and not participate in any promiscuous behavior. For me to be promiscuous is to shame and reject the very One whom I worship and put my trust in.
Based on what I understand of Scripture (my personal opinion), being gay is just another manifestation of our sinful nature that needs to be placed at the foot of the Cross. All of us sin and will continue to sin the rest of our lives, but my hope is that we will begin to sin less, though we will never be (sinless) until we meet our Saviour and Lord face to face.
