Christian have the monumental admonition to “pray without ceasing.” Over a thousand years before this, under the lesser light of revelation of the Old Testament, there was a man who lived the same teaching, King David.
3:1 O LORD, how my adversaries have increased!
Many are rising up against me.
2 Many are saying of my soul,
"There is no deliverance for him in God." Selah.
3 But Thou, O LORD, art a shield about me,
My glory, and the One who lifts my head.
4 I was crying to the LORD with my voice,
And He answered me from His holy mountain. Selah.
David was surrounded by an ever increasing number of enemies. They mock, they ridicule, and the specifically attack him for his faith in God. God is still the shield, glory, and power of David. These attacks did not drive David from God, but closer to Him.
David was not disappointed in his hope in God, but He was answered and could go in peace because of it. Selah — stop and think about God answering prayer.
God is approachable in prayer. He answers prayer, He delivers the oppressed. Thus, as Jesus said, “Peace I leave with you; My peace I give to you; not as the world gives, do I give to you. Let not your heart be troubled, nor let it be fearful.” (Jn. 14:27)
