Today's Lesson from 1 Kings 19: 
4 But Elijah himself went a day's journey into the wilderness and came and sat down under a broom tree. And he asked that he might die, saying, “It is enough; now, O Lord, take away my life, for I am no better than my fathers.” 5 And he lay down and slept under a broom tree. And behold, an angel touched him and said to him, “Arise and eat.” 6 And he looked, and behold, there was at his head a cake baked on hot stones and a jar of water. And he ate and drank and lay down again. 7 And the angel of the Lord came again a second time and touched him and said, “Arise and eat, for the journey is too great for you.” 8 And he arose and ate and drank, and went in the strength of that food forty days and forty nights to Horeb, the mount of God.

Rollo May said depression is the inability to construct a future. That is Elijah. Emotionally spent and afraid, Elijah is now at the point of emotional paralysis. Though he was a great instrument of God in the past, he can no longer see a meaningful future for himself. Then the angel appears with a cake and water. "Arise and eat," he says and Elijah does.

In this text the word "angel" could be simply translated "messenger". I am thinking, maybe you know somebody who can no longer imagine the future. How bout dropping off a cake or a card or perhaps calling? You could be the messenger from the future they don't even know exists.
