One such passage for me (and there are many!) is Isaiah 40:10-11. "Here comes with power the Lord God, who rules by his strong arm; here is his reward with him, his recompense before him. Like a shepherd he feeds his flock; in his arms he gathers the lambs, carrying them in his bosom, and leading the ewes with care." My first thought is, "What does being a shepherd have to do with God ruling with power?" But it seems that being a shepherd goes with the second part of verse 10, "here is his reward with him, his recompense before him." The flock is his reward and he guards it with his strong arm, particularly the ewes and the baby lambs.
We know that we are that flock. He guards us, especially the mothers and young children, with his strength, his power. And he who created the world and all that is in it (vv. 12-14) is eminently capable of providing for the flock.
What is there that we need that God cannot provide? Nothing.
Let us pray. You measured the waters in the hollow of your hand. You marked off the heavens with the breadth of your hand. You held the dust of the earth in a basket and weighed the mountains on scales. You call each star by name. We are like a drop in a bucket, like grasshoppers, yet we cannot hide from you. You are the everlasting God, the Creator who does not grow tired but gives strength to the weary and power to the weak. You renew our strength through hope in you and we soar on wings like eagles.
