The prayer life does not consist of perpetual repetition of petitions. The prayer life consists of life that is always upward and onward and Godward

Those who wait for God are pilgrim souls that have no tie that will hold them when the definite command is issued; no prejudices that will paralyze their effort when in some strange coming of the light they are commanded to take a pathway entirely different to that which was theirs before; having no interests either temporal or eternal, either material or mental or spiritual, that will conflict with the will of God when that will is made known.

If you have no opposition in the place you serve, you're serving in the wrong place.

Waiting for God is not laziness. Waiting for God is not the abandonment of effort. Waiting for God means, first, activity under command; second, readiness for any new command that may come; third, the ability to do nothing until the command is given.
