"Oh come, let us sing to the Lord; let us make a joyful noise to the rock of our salvation! Let us come into his presence with thanksgiving; let us make a joyful noise to him with songs of praise! For the Lord is a great God, and a great King above all gods. In his hand are the depths of the earth; the heights of the mountains are his also. The sea is his, for he made it, and his hands formed the dry land. Oh come, let us worship and bow down; let us kneel before the Lord, our Maker!"
"If God truly is a great God, then how should we respond to His greatness?
First, thank Him. "Let us come before His presence with thanksgiving; let us shout joyfully to Him with psalms" (v. 2). Be thankful that He is a great God. Note that His greatness extends to creation. "In His hand are the deep places of the earth; the heights of the hills are His also" (v. 4). Isn't it good to know that God is a God of the depths as well as a God of the heights? When we're living on the mountaintop, He is there. When we're down in the valley, He is there. "The sea is His, for He made it; and His hands formed the dry land" (v. 5). I'm glad that my God is God of the changing places, such as the sea, and of the stable places, such as the dry land. No matter where we are, we can experience His greatness.
Second, sing to Him. "Oh, come, let us sing to the Lord! Let us shout joyfully to the Rock of our salvation" (v. 1). And worship Him. "Oh, come, let us worship and bow down; let us kneel before the Lord our Maker" (v. 6).
The greatness of God is the answer to the smallness of man. When you see great sin and great disappointment or when you have a great burden to carry, remember that you are worshiping a great God. As you kneel before Him, He becomes even greater."
