The wise R. A. Torrey (1856-1928) wrote, “There is no blessed training in prayer than that which comes through being compelled to ask again and again, over long periods of time. Before obtaining what we seek from God. Many people call it submission to the will of God when God does not grant them their requests on the first or second asking. They say, “Well, perhaps it is not God’s will.”
As a rule this is not submission, but spiritual laziness. We do not call it submission to the will of God when we give up after one or two efforts to obtain things by action; we call it lack of strength of character. When the strong man of action starts out to accomplish a thing, if he does not accomplish it the first, or second or one hundredth time, he keeps hammering away until he does accomplish it; and the strong man of prayer when he starts to pray for a thing keeps on praying until he prays it through, and obtains what he seeks. We should be careful about what we ask from God, but when we do begin to pray for a thing we should never give up praying for it until we get it, or until God makes it very clear and very definite to us that it is not His will to give it.
“At all times you ought to pray and not to lose heart.” Jesus
