From Pastor’s Desk:
Psalm 37:4 (NASB) Delight yourself in the Lord; And He will give you the desires of your heart.
Allow me to present comments from commentators:
Adam Clarke: Delight thyself also in the Lord] Expect all thy happiness from him, and seek it in him.
The desires of thine heart.] twlavm mishaloth, the petitions. The godly man never indulges a desire which he cannot form into a prayer to God.
Family Bible Notes: Delight in the character, will, and ways of God is a means of increasing excellence, usefulness, and enjoyment.
Jamieson, Fausset-Brown: desires– (Ps 20:5; 21:2), what is lawful and right, really good (Ps 84:11).
So, can we not conclude that the desires of our hearts must line up with God’s will? We cannot expect to live a life apart from God and not adhere to His word and then reap all those things we desire.
If we are delighting ourselves in the Lord, we can expect, even anticipate, the wondrous works, revelations, benefits, etc., given us from His bountiful storehouse of love, from which He bestows grace, mercy, compassion, and all things we need to victoriously live, to be ours for the asking. And most times, if we’re living in the right way, we don’t even have to ask. He just supplies all our needs according to His riches in glory (Phil. 4:19).
Now, the phrase that is most significant in the verse is “in the Lord.” If our delight is in something or someone else we cannot expect of Him all the above.
