The word translated ‘commit’ is literally ‘roll’, or ‘roll away’. Something too heavy to lift must be rolled, and in this case it is rolled into the Lord’s hands, so that the translation ‘commit’ is exactly right.
We must completely surrender our will to the Lord when we seek his guidance and be ready for him to lead us in a way that is contrary to our natural inclinations and that may cut across our long held customs and practices.
