Psalm 35:9 Then I will rejoice in the Lord. I will be glad because He rescues me.
David knew, knew without doubt that God would rescue him in times of trouble... David knew he was going to rejoice... that he was going to be rescued. We we walk with God we can be as sure as David was that God will rescue us! We can rejoice now in the knowing and rejoice later in God's doing!... How wonderful is that!
