"Trust in the Lord, and do good; so shalt thou dwell in the land, and verily thou shalt be fed. Delight thyself also in the Lord; and he shall give thee the desires of thine heart. Commit thy way unto the Lord, trust also in him; and he shall bring it to pass. And he shall bring forth thy righteousness as the light, and thy judgment as the noonday. Rest in the Lord, and wait patiently for him, fret not thyself because of him who prospereth in his way, because of the man who bringeth wicked devices to pass. Cease from anger, and forsake wrath: fret not thysef in any wise to do evil." Psalm 37:3-8
We are admonished to trust, delight, commit, rest in the Lord, and cease from anger. If we trust in the Lord and do good, we shall be secure, and our needs will be met. When we delight in the Lord, he will give us the very desires that enter our heart, those things we so greatly desire will be from God, and he will cause our desires to become reality according to his will and purpose. If we commit ourselves to him, he will bring it to pass.
We can rest in the Lord and wait patiently for him to bring to pass all that will be good for us, and bring glory to himself. We can have perfect peace when we cease from anger and forsake wrath, and harbor no thoughts of doing evil.
