"The Lord is my Rock, my Fortress and my Deliverer; my God is my rock, in whom I take refuge, my shield and the horn of my Salvation. He is my Stronghold, my refuge and my Savior-- from violent people You save me." 2 Samuel 22:2, 3)
This is Jesus Christ. Remember: only one Lord, not an Old Testament one and a New Testament one. This is Who Jesus Christ is to you and me, to all who surrender their lives to Him.
Our text is found in Psalm 18; therefore, the next time you read either 2 Samuel 22 or Psalm 18, MAKE SURE you read 2 Samuel 21 first, and, take particular note. You'll see the reason.
