I can do all things through Christ who strengthens me (Php 4:13)! He is my life and by faith I know He is in me and is faithful to intercede and make me hit the mark of God's glory (Heb. 7:25). God's glory is made perfect when we rest in Him, trust His word, and stand against the fallen facts of this realm. We speak God's word and pray His will into our life situations because He is in us to fulfill His purposes.
When we acknowledge that our strength and purpose is God's gift to us we are staying in His grace (Philemon 1:6). I speak His word over against any lack in my life (Mark 11:23). I speak His word over against any sickness in my life. I do this because His word authorized me to use His name, peace, position, and righteousness to command God's will done in my life (John 14:14). I speak and then walk towards that mountain to see it move away by the miracle working power of God.
