Psalms 54:6-7

David was so sure that God would deliver him that he spoke of offering a freewill sacrifice of worship for God’s deliverance. This would have been the peace (fellowship) offering (Leviticus 3; Leviticus 7). He believed God would deliver him because God is good (cf. Psalms 52:9). In Psalms 54:7, the psalmist spoke of his deliverance as already past, as a way of expressing his confidence in God. He would have found satisfaction in God punishing his enemies for their evil, not because he hated them personally.

When God’s people experience opposition from others who seek to thwart His will, they can count on His eventual deliverance. It may not come this side of the grave, but God will punish evildoers and reward those who trust and obey Him. [Note: See Swindoll, pp. 141-51.]
