"But grow in the Grace, knowledge, and understanding of the Lord Jesus Christ ", Peter said in II Peter 3:18. It's not by our power that we do so, but according to the working of HIS mighty power in us. We simply yield our lives to HIm to work in us to will and then do what He desires, and by Grace through faith, He takes us beyond our present capacities spiritually, mentally, emotionally, and even physically, and we find ourselves being changed from glory to glory!
