Ask Tamara: Out of the Closet!

During a recent family gathering, my youngest brother announced that he is gay. The entire family was shocked, including me. I never suspected that my brother was gay. Growing up he had plenty of girlfriends and didn’t show any signs of being gay. I haven’t spoken to him since his big announcement and am really unsure about what to say or how to handle the situation.
On one hand I want to support my brother and let him know that I still love him, but on the other I am really worried about him. Our family grew up in the church and this is not the way we were raised. I don’t agree with my brother choosing to live a gay lifestyle, I think homosexuality is a sin and I don’t want him to suffer. What can I do about this?
