I trust in the steadfast love [mercy] of God
forever and ever.
I will thank you forever,
because you have done it.
I will wait for your name, for it is good,
in the presence of the godly.
—Psalm 52: 8-9
C. H. Spurgeon comments, “Eternal mercy is my present confidence. David knew God’s mercy to be eternal and perpetual, and in that he trusted. What a rock to build on! What a fortress to fly to!”
