One does not surrender a life in an instant. That which is lifelong can only be surrendered in a lifetime. Nor is surrender to the will of God (per se) adequate to fullness of power in Christ. Maturity is the accomplishment of years, and I can only surrender to the will of God as I know what that will is.
