Here the psalmist David does what he does best - he offers praise to the Almighty God.
"Praise God!" he says, "Don't forget all the good things He has done for you." Then he proceeds to give a list of what God has done:
Psalm 103 is one of exuberance and praise for the God who has done wonderful and mighty things for man who is as fleeting as grass (verse 16).
Sometimes, we focus on the wrong things. We forget that life is a great gift which God has given us only because He is gracious and does not treat us as we deserve.
David is reminding us of the good things that God has done. Through his example, we learn to praise Jehovah for He is an awesome God.
Just like David, we need to take time each day to give thanks to God for the things He has done for us.
Let all that I am praise the Lord; may I never forget all the good things he has done for me.
