Few praise God when life is full of disappointment. Of course we should, but faith seems to take strength in its celebrations, not its commiserations. Is this the praise which comes from victory over the Philistines recorded immediately before (21.15-22)? Possibly. Maybe it comes from a far happier season in David’s life, say, at the happy arrival at Jerusalem? Whatever its setting, our challenge is that God’s praises must be in our hearts “through all the changing scenes of life, in trouble and in joy”.
Because God is worthy. He is always mighty, merciful, utterly reliable, always strong to save, always rescuing in His grace (vv.1-4).
Because grace is personal. You have danger, tears, stress? Cry out to God, discover His power to save you, as David did (vv.5-7).
Because God is mighty. God is never more glorious than when He’s confessed by His church as the Triune Lord of His Word. He is yet more glorious when He is seen to be at work, displaying the might of that Triune name in acts of judgement and salvation (vv.8-20).
Because noone deserves salvation. Don’t misread David’s confession as smug pride and desperate lack of self-awareness. This is not pride before a fall. This is a grace-adopted child of God rejoicing that because of grace he can be confident of grace. The God who gave him a heart to seek Him gives him power and joy in obedience, and a ready answer for his prayers (vv.21-25).
Because courage comes from God. He reveals Himself, and does so clearly in His Word. He is the shield and the encourager and trainer of all who fight in His name. He gives strength and He brings victory (vv.26-47). Do you know this God?
Because God Lives. Idols falls, dreams fade, and even temptations lose their power. God endures, and shall endure forever. He is the Rock, and must be the praise of our hearts, lips and lives (vv.48-51). In Jesus this song of David truly sings. Jesus is the One exalted to conquer, and by His Cross and Resurrection He has.
A Prayer to Pray
God of Grace! Thankyou for this wonderful song, which by grace can by my song. Please, be the Lord of my heart, the One who brings Your strength and joy to my needy life. Amen.
