Discovering the power in the word of God is all that the centurion needed to have his servant who was grievously tormented by palsy healed. This is what many that have been coming to God lack and therefore deny themselves begging miracles.  Mt.8:5-13; Lk.5:17; Heb.4:12-13; Acts 8:5-7

God, who has magnified His word above His name (Ps.138:2) has vested the power to change and judge situations on His word (Jn.1:1-3; Jn.12:48). So, our attitude to the word of God at our disposal determines what we get from God.
