For our Psalm today I've chosen 103, which is a little longer than the others we have looked at so far. What intrigued me is in verse 2: Praise the Lord, O my soul, and forget not all his benefits. Then it lists various benefits for which we should praise God just in case you can't think of any yourself. So if you have had a long, hard day, and you are stressed or depressed, this Psalm's for you.
The author (pehaps David) must have been having a bad day because in this Psalm he is talking to himself. "Praise the Lord, O my soul." He is giving himself a pep talk. We all have days like that. Everything has gone wrong. So if you've been talking to yourself and no one is giving you the pep talk you need, this Psalm's for you.
A few of God's benefits - he forgives all of your sins, heals all your diseases, and redeems you from the pit. He is slow to anger and quick to love. If you are oppressed, he works for righteousness and justice. He keeps his covenant. He satisfies your desires with good things so that your youth is renewed. So if you are feeling old, sick and tired, this Psalm's for you.
There are a lot more benefits listed than can be covered here. So read it for yourself. This Psalm's for you.
