Prayer is an important indicator of our faith. It is an expression of our conviction that God is in control. One who does not truly believe prays in vain.
Prayer Opens Doors PP
2 Continue earnestly in prayer, being vigilant in it with thanksgiving; 3 meanwhile praying also for us, that God would open to us a door for the word, to speak the mystery of Christ, for which I am also in chains, 4 that I may make it manifest, as I ought to speak.
