Psalms 4:3

"But know that Jehovah hath set apart for himself him that is godly:

Jehovah will hear when I call unto him.

Stand in awe, and sin not:

Commune with your own heart upon your bed, and be still. (Selah)"

The greatest of all blessings is that of belonging to that special group of human beings whom God has set apart from all mankind as his very own people. God will nurture and encourage his children; he will hear them when they pray; he will forgive their sins and mistakes, provided only that they repent, acknowledge their lapses and seek the Father's loving forgiveness.

"Stand in awe, and sin not." The perpetual danger to God's children is that they might presume upon his love and mercy and fail to manifest the proper fear and awe of all sinful indulgences whatsoever; hence the special warning here.

"Commune with your own heart." What is recommended here is the most serious consideration of one's actions with a constant view of making sure that they confirm to the will of God. When one has retired to bed at night is a good quiet time for such consideration. David himself practiced what he here counsels others to do, namely, meditating upon God's will while reclining in bed (Psalms 63:6).
