In Psalm 71:15, David wrote, “My mouth shall tell of Your righteousness And of Your salvation all day long; For I do not know the sum of them (NASB).” It’s an interesting phrase in that in the last line he admits he does not know the sum, the totality of God’s righteousness and salvation. Even though he does not understand the depth of God’s love, he will profess it “all day long.”
As humans we have a desire to know, to understand. We seek knowledge about many things, wanting to comprehend what they are about. Often we try to understand God, sometimes growing frustrated when what is happening to us does not make sense. We cannot grasp the sum, the totality of God’s righteousness and salvation.
Yet David reminds us to not just trust God, but to speak about God’s righteousness and salvation “all day long.” We can tell others about how God’s love and grace for us is so expansive that it is beyond our comprehension. We cannot compare it to anything on this earth.

And even when I am old and gray, O God, do not forsake me, Until I declare Your strength to this generation, Your power to all who are to come. For Your righteousness, O God, reaches to the heavens, You who have done great things; O God, who is like You? – Psalm 71:18-19
