[God says,] "Before I formed you in the womb I knew you, before you were born I set you apart; I appointed you as a prophet to the nations."
What an awesome feeling it is to know that your destiny is still in the forming stage. Don't worry about friendships that do not last or people who walk out of your life; they are not supposed to be with you when God's purpose in your life is fulfilled. In the meantime, concentrate on Him and the direction He has for you. Before you know it, all the things you have been set apart from seem meaningless. Could the problem be you are still holding onto what God is trying to set you apart from?
