Here is a lovely passage from psalm 85.11:
Faithfulness springs forth from the earth,
and righteousness looks down from heaven.
Parallelisms such as this one is used in Biblical Hebrew poetry to indicate when two things are connected in some way.
But, what is the link? Righteousness belongs to heaven, granted – but one does not readily associate the earth with faithfulness.
Paul the Apostle (Rom 3:9-18) makes it abundantly clear that there is no one righteous (quoting Ps 15, Ps 53 and Ecc 7). Humans are also notoriously faithless and adulterous throughout the Bible and in our own experience.
So, what faithfulness can possibly spring forth from the ground?
The Root of Jesse (Isaiah 11:10; Rom 15:12): Jesus
The the righteousness of God is revealed in the Gospel, in the person of Jesus (Rom. 1:17), and Jesus himself being God, is seated at the right hand of the Father, looking down from heaven.
God has done it all. Jesus was faithful to his Father. Jesus was found righteous.
We too can be found faithful and righteous if we are found in the God-man Jesus.
