Entering into David's story with God (especially as recorded in the Psalms), you’ll see David continued to GAIN a greater understanding of BOTH the MAGNITUDE and INTIMATE NATURE of God. He found what we can find -- even in today's world -- a growing knowledge, understanding, and appreciaton of God.
O LORD, you have searched me and you know me. You know when I sit and when I rise; you perceive my thoughts from afar. You discern my going out and my lying down; you are familiar with all my ways. Before a word is on my tongue you know it completely, O LORD. You hem me in - behind and before; you have laid your hand upon me. Such knowledge is too wonderful for me, too lofty for me to attain.
How do you know you are growing? You'll learn to TRUST God more fully, you'll be able to RELY on Him in all circumstances, and you'll ultimately find REST and PEACE in Him.
