Psalm 37:5–6 (ESV) … “Commit your way to the Lord; trust in him, and he will act. He will bring forth your righteousness as the light, and your justice as the noonday.”
That word “commit” is a verb with an interesting meaning. It literally means “to roll over.” God doesn’t take our burdens so that we can become irresponsible, but so we can serve Him better. The suggestion here is that we should take our great burdens and roll them over on Him.
Now, this isn’t a careless attitude but one that trusts the Lord. It is an attitude that remembers that God is working his divine will on a grand scale. It understands that God is not going to be hustled and hurried by our fretting.
Old Testament scholar and an authority on liturgics, H. C. Leupold says, this word “commit” is the idea to “dislodge the burden from your shoulders and lay it on God.”
This is what the apostle Peter was thinking about in 1 Peter 5:7—in fact, he was probably referring to Psalm 37:5 explicitly—when he wrote, “Cast all your anxiety on him because he cares for you.”
Peter tells us that we do not need to worry about things, because God cares for us, is equal to all circumstances, and will manage anything that can possibly come into our lives.
Finally, those who obey this counsel shall escape that horrible maze in which all labor in vain and that being to worry. For when God takes the management of our affairs into his own hand, there is no reason to fear that His love shall ever fail us. If therefore, we would only permit God, he will perform His part, and will not disappoint our expectations and hope.
