3. God's responsiveness to prayer 145:17-21

Everything the Lord does is right. Kindness also marks all He does. He is attentive to those who pray to Him sincerely. He will grant the petitions of believers and will deliver them in times of need. He will protect those who love Him but will destroy those who do not. For these reasons David said he would praise Yahweh and all people will bless Him forever.

This psalm is a great catalogue of reasons to praise God. Like the other acrostic psalms it is a model for us to use in recalling many of the things about God for which we should praise Him.
