Should there be an issue on gay couples adopting children? Who am I to judge others? I'm not perfect. In my flesh, I sin. So I am not one to pass judgement onto others. Hey, maybe they'll do a better job than most parents. You'll never know. But to be honest, a family in Christ, is a happy family. As long as you have Christ, you're set. I don't know how this answers your question, and all, but it's my opinion. And others shouldn't be to quick to judge either. Unless they're perfect, they have no right to pass judgement onto a fellow human being. If a Christian for example passes judgement onto another human being, in this case, gay couples, they'll only be contradicting themselves and indirectly they'll make themselves hypocrites. God says to love one another and not judge, yet, in the society we're living in, judgement is like a basic necessity. God loves all man. And God treats all man equally. And He's God. Why can't we do that same?
God bless, and have a good day.
