There are some people who want to show God the goal and to determine the time and the manner and at the same time suggest how they wish to be helped; and if things do not turn out as they wish, they become faint-hearted, or, if they can, they seek help elsewhere. They do not wait upon God, rather God should wait for them and be ready at once to help them in the way they have planned. But those who truly wait upon God ask for grace, and they leave it free to God's good pleasure how, where, and by what means He shall help them. They do not despair of help, yet they do not give it a name. They rather leave it to God to baptize and name it, however long it may be delayed. But whoever names the help does not receive it, for he does not await and suffer the counsel, will, and tarrying of God.
Martin Luther, Exposition of Four Comforting Psalms, 1526 (EA 37:423)
