PSALM 37:3

3...Trust (have confidence) in the Lord (the one who rules all; highest power), and do good (positive/desirable in nature); so you will dwell (live/exist in) in the land, and in truth you will be fed (given food; supplied with nourishment).

IN OTHER WORDS...

If we choose to live our lives in the desirable nature by which we were created and which we know to be pleasing unto God, we must then have faith in the Lord who rules over all Heaven and earth to believe that our choice to live according to the commandments of God will produce in our lives the inevitable certainty that the reward for our positive living will be the truth of God, the glorious truth of his word by which those who are anointed to live in the land of his ruling will be provided as food for the divine nourishment of their mind, heart, body and soul.

Although my focus is on verse 3, I implore you to please read the entire chapter to see just how blessed the righteous in living truly are under the hand of God.

To the Lord Jehovah be the glory for the reading, understanding and edification of his word.
