Trust in the Lord, and do good; so you will live in the land, and enjoy security. Take delight in the Lord, and he will give you the desires of your heart. (Psalm 37: 3-4)

If X then Y. If we trust in God and do good then there will be a specific outcome.

If you take delight in God then the desires of your heart will be fulfilled.

Absent delight in God the desires of our heart might be A. Filled with delight in God the desires of our heart might be Z. The predicate defines the subject.

If we love the Lord or God with all our heart, our soul, and our strength...

Then we shall love our neighbor as ourself. (Mark 12: 30)
