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.
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.
