How wrong it is to use God as a stop-gap for the incompleteness of our knowledge. . . . We are to find God in what we know, not in what we don't know; God wants us to realize his presence, not in unsolved problems but in those that are solved. . . . God is no stop-gap; he must be recognized as the center of life, not when we are at the end of our resources.
Dietrich BonhoefferTrue prayer is done in secret, but this does not rule out the fellowship of prayer altogether, however clearly we may be aware of its dangers. In the last resort it is immaterial whether we pray in the open street or in the secrecy of our chambers, whether briefly or lenghtily, in the Litany of the Church, or with the sigh of one who knows not what he should pray for. True prayer does not depend either on the individual or the whole body of the faithful, but solely upon the knowledge that our Heavenly Father knows our needs.
Dietrich BonhoefferTo be sure, God shall call you, and us, only at the hour that God has chosen. Until that hour, which lies in God's hand alone, we shall be protected even in the greatest danger; and from our gratitude for such protection ever new readiness surely arises for the final call
