What does the Bible say about homosexuality and same sex marriage?

There has been a lot in the news about this subject. There are TV shows that promote the homosexual and make it a live happily ever after life style.
In the United States gays and lesbians can legally marry in New Hampshire, New York, Massachusetts, Connecticut, Iowa, Vermont, and Washington, DC.
My concern is our children and our grandchildren are growing up in a perverse Nation and society. Is this the first time that there has been a perverse Nation and society? Can it be forgiven? What does God say about homosexuality?

Leviticus 18:22 Thou shalt not lie with mankind, as with womankind: it is abomination. and Leviticus 20:13 If a man also lie with mankind, as he lieth with a woman, both of them have committed an abomination: they shall surely be put to death; their blood shall be upon them.
I was in a discussion just this week with some folks and I quoted an Old Testament scripture and their reply was "well, we don't live in the Old Testament now, we live in the New Testament of grace." My reply was, God says He is the same yesterday today and forever and He change not, there was a little over 400 years between the Old Testament and the New so do you think that God changed in those few years?

Listen folks, there is a continuous revelation of the wrath of God in both the Old Testament and New Testament. It is re-vealed in our contemporary society. This is God’s constant and insistent displeasure with evil. He changes not. God is merciful, not because He is lenient with the sinner, but because Christ died. The gospel has not changed God’s attitude toward sin. The gospel has made it possible to accept the sinner. The sinner must have either the righteousness or the wrath of God there is no other choice and that choice is ours and sad to say, many will choose their on way.

The New Testament talks about homosexuality also but, I just wanted to make a point about the Old Testament and New because, they are both instructions and Gods divine word for mankind. Look at what the New Testament says in Romans 1:25 Who changed the truth of God into a lie, and worshipped and served the creature more than the Creator, who is blessed for ever. Amen. 26 For this cause God gave them up unto vile affections: for even their women did change the natural use into that which is against nature: 27 And likewise also the men, leaving the natural use of the woman, burned in their lust one toward another; men with men working that which is unseemly, and receiving in themselves that recompence of their error which was meet.

Verse 25 of Romans chapter 1 says that they changed the truth of God into a lie. Ellen DeGeneres is an American poster for the homosexuals so to speak that says, it's OK to be gay Moms and Dads, teach your children to love and accept the way I am and others like me. Is it OK to be gay? Is gay marriage OK?
Look, it's not OK....Bible says it's an abomination
