The bible says that for a man/woman to be with the same gender as like in a marriage is wrong.
I personally do not see how it affects me physically or otherwise if the same gender chooses to get 'married', (I'm using that word as it's easy and everybody knows what it means), not because I'm advocating its existence. But as a child of God, because I do believe in his word, because I do want to do his will, if God says it's wrong then I must preach that; so must other Christians.
So now I'm hearing the words 'free will' has come into some of your minds - whatever - I do believe it is a sin. Ultimately what I'm saying is this:
The way to get to heaven is to repent of your sins, believe in God with all of your heart and soul, believe that Jesus is the way and by the grace of God you may be saved.
No doubt all you unbelievers will twist all what I said somehow and anyhow you want but I know what I said and so does God.
That is all I'm going to say on the matter.
