"Delight thyself also in the LORD: and he shall give thee the desires of thine heart." (Psalm 37:4)
Psalm 37 provides cures for the fretting (Hebrew charah, "anger") that comes in a spiritual battle. These emotions explode from the heart of the righteous saint against those who would dare lift up their hand against the Lord.
This beautiful promise and command insists that we luxuriate in our Lord. He is the Lord of inexhaustible riches (Philippians 4:19) and His inexpressible power is at work in His children (Ephesians 3:20).
Isaiah records God’s rhetorical question: "Wherefore do ye spend money for that which is not bread? and your labour for that which satisfieth not? hearken diligently unto me, and eat ye that which is good, and let your soul delight itself in fatness" (Isaiah 55:2). God reminded Israel that the day was coming when they would "be delighted with the abundance of |Jerusalem’s| glory" (Isaiah 66:11).
Jesus also said, "How much more shall your Father which is in heaven give good things to them that ask him?" (Matthew 7:11).
When we trust the Lord to give us what we need, is it any wonder that He who knows all and owns all will give us the desires of our hearts? If we long for the kingdom of God and His righteousness, why should we marvel when the King of kings grants our desires?
The delight that we have in the work and ministry of the Lord is the key to His answering our "effectual fervent prayer" (James 5:16).
Simply stated, a human heart that is aligned with the beat of the Divine heart will receive God’s bountiful answers (Deuteronomy 5:29). HMM III
