Robert Speer said, “The evangelization of the world depends first of all upon a revival of prayer. Deeper than the need for workers; deeper far, than the need for money; deep down at the bottom of our spiritual lives is the need for the forgotten secret of prevailing, worldwide prayer. Missions have progressed slowly abroad because piety and prayer have been slow at home.”
Robert Speer is right; prayer is evidence of our utter dependence on God. Without Him we can do noth- ing. However, never forget that Jesus said there was a lack of laborers in His time, and there is a lack of la- borers in our time (see Matt. 9:37). It is easier to pray for this world than to preach the gospel to them. So make sure that you don’t substitute the sacrifice of prayer for the obedience of evangelism; to do so is to play the hypocrite.
“We Christians too often substitute prayer for playing the game. Prayer is good; but when used as a substitute for obedience, it is nothing but a blatant hypocrisy, a despicable Pharisaism…To your knees, man! And to your Bible! Decide at once! Don’t hedge! Time flies! Cease your insults to God. Quit consulting flesh and blood. Stop your lame, lying, and cowardly excuses. Enlist!” C. T. Studd
Matthew 21:22 And whatever things you ask in prayer, believing, you will receive.”
