I am worn out from waiting on God. Do I make a move myself, or is that just running ahead of him?

“Wait on the LORD: be of good courage, and he shall strengthen thine heart: wait, I say, on the LORD.”

David wrote this psalm from somewhere between confidence and threat, surrounded by enemies and still asking to sit in God's house. The closing line is addressed to himself, which matters: this is a man talking his own tired heart into holding position. Courage appears here as part of waiting rather than as the alternative to it, which is a very different picture from passivity.

“For ye have need of patience, that, after ye have done the will of God, ye might receive the promise.”

The recipients of this letter had already lost property and social standing for their faith, and the early rush of conviction had worn thin. The writer offers them no shortcut. He names endurance itself as the thing still required and locates the promise on the far side of it. That is written to people whose main experience of faith at that point was fatigue.
