When I read this chapter I can feel the confidence that David has in God, after all, it was the Lord Almighty that saw him through so many trials and brought him victory. With a heart of thanksgiving, David casts one eye back on his life to see where God had mercifully saved him and rejoices about it. And yet at the same time, the spirit of prophecy works through him to cast the other eye firmly into the future and gaze upon the figure of Jesus Christ.
For just a moment David catches a glimpse of the promise that will save not only him but all of mankind. He did not know how or who exactly but he knew that God's word is true and he trusted that truth to hold firm. David had confidence in God then, so we should have even more confidence in the Almighty today! After all, Jesus in you IS the victory!
This chapter is held together by the bookends of "prayer" and "praise". When I read the first two verses I immediately thought of the prayer of Jesus in John 17:9,20; as He prayed for, first the disciples and then for the church. When we receive the gift of the Holy Ghost and then hold onto that promise with all our might, nothing can snatch us out of our Father's hands, all because "THE" King prayed. Now all we need to do is praise Him for all He has done for us, and let hell know who has the Victory!
O death, where is thy sting? O grave, where is thy victory? ( 1 Cor 15:55 )
