He is the God of judgment. He is the God of wrath. He is the God who hates sin. That is what the Psalmist does here in verse 2. He knows that there is a kind of spiritual sluggishness in these things.
Memory is so important in the Christian life.
Praise the LORD, O my soul, and forget not all his benefits . Again this is a command. It is a command to put your mind to remembering the goodness of God in your life. It is so easy to complain about the way God is treating you. That is what the Children of Israel frequently did in the desert.
