Charles H. Spurgeon on Psalms 37:5

Commit thy way unto the Lord, etc. When we bear the burden of our own affairs ourselves, and are chastised with anxiety and want of success, and with envying the ungodly who prosper better than we do, the best remedy is first to do our duty, as we are enabled in the use of the means, then cast the care of the success over on God, as the ploughman doth when he hath harrowed his land; and let the burden of it rest on God, and let us not take it off him again, but put our mind to rest, resolved to take the harvest in good part, as he shall send it. David Dickson.
