Throughout the Bible we are exhorted again and again to trust in the Lord. We are warned against trusting in princes, in riches, or in ourselves; for all such trust is vain. Trusting in the Lord is represented as being safe, as blessed, and as producing very desirable results. In it is our hope, our strength, our safety, and our help. In Whispers of God's Assurance: Psalm 23, the author tells of the assurance of four promises of God etched within what is the most popular psalm known to man.
