Joshua 1:9 - "Have I not commanded you? Be strong and courageous. Do not be afraid; do not be discouraged, for the LORD your God is with you wherever you go."  

Those Believers who are pursuing their calling in Christ have to be risk takers -- getting into deep water is scary because there's a possibility that you could drown.  Getting into the water is scary because it's cold. But getting in is the only way you will learn to swim. You can't learn hanging on the edge.  

Getting to the next level of God's purpose for your life works the same way; you will have to step out of what feels secure. Our destiny is waiting on the other side. We can't let fear keep us from moving forward doing what we have been created to do.
