Let go, because God has better things ahead than anything He asks me to leave behind. He has even told me, "I have greater things planned for you." So trust Him, and have faith. Be obedient and let Him have His way.
When I call you to go through the deep waters I will be with you! I will not let you sink nor let the waves overcome you! When you walk through the fire you will not get burned! I am the Lord thy God [paraphrase]
