Obama:"If my people, which are called by my name, shall humble themselves, and pray, and seek my face, and turn from their wicked ways; then will I hear from heaven, and will forgive their sin, and will heal their land."
God isn't addressing the non-believer in that verse. He's directing "my people called by my name" first the Jew, now the Christian.
Don't you believe He's powerful enough to to overpower evil in the land if we repent and pray? The problem is that Chrisians are no different from pagan society today.
It's not too late!
