I denounce unto you this day, that ye shall surely perish, and that ye shall not prolong your days upon the land, whither thou passest over Jordan to go to possess it. I call heaven and earth to record this day against you, that I have set before you life and death, blessing and cursing: therefore choose life, that both thou and thy seed may live: that thou mayest love the Lord thy God, and that thou mayest obey his voice, and that thou mayest cleave unto him: for he is thy life, and the length of thy days: that thou mayest dwell in the land which the Lord sware unto thy fathers, to Abraham, to Isaac, and to Jacob, to give them.
~ Deuteronomy 30:18-20 (KJV)
And for those who don't speak 400-year-old Elizabethan English:
But I warn you: If you have a change of heart, refuse to listen obediently, and willfully go off to serve and worship other gods, you will most certainly die. You won’t last long in the land that you are crossing the Jordan to enter and possess.
I call Heaven and Earth to witness against you today: I place before you Life and Death, Blessing and Curse. Choose life so that you and your children will live. And love God, your God, listening obediently to him, firmly embracing him. Oh yes, he is life itself, a long life settled on the soil that God, your God, promised to give your ancestors, Abraham, Isaac, and Jacob.
~ Deuteronomy 30:18-20 (The Message)
