Psalm 72 is titled " A Psalm of Solomon".   Here we have a description of a perfect King...

Although Solomon was given the gift of wisdom and knew these truths, he failed to fulfill these traits. Christ alone is the King of Righteousness.

Jesus has the "judgements" of God.
He has absolute "righteousness".
He judges perfectly.
He brings justice for the afflicted.
He brings peace to His people.
He vindicates the afflicted.
He saves the needy children.
He crushes the oppressors.
He endures for all generations.
He is like the rain, providing for the needs of His people.
His kingdom will flourish with peace and righteousness.
His rule extends over all the earth.
Every nation, tribe, and people will bow before Him.. from the nomad to the king,  from the wilderness to the farthest island.

Jesus "will deliver the needy when he cries for help.."
He comes to the aid of those who have no other help.
"He will have compassion on the poor and needy." 
He is our rescuer from oppression and violence.
Our blood is precious in his sight.
In the Kingdom of God there will be abundance forever.
His Name will endure.
He is call Blessed.
He "alone works wonders." 
"..May the whole earth be filled with His Glory."
Amen and amen.

There has never been, nor will there ever be a human king that can stand up to this standard.
We can only pray that the Lord will have mercy on us and that He will bring the hearts of our leaders into alignment with His will.

Father, we pray for Your kingdom to come and Your will to be done on earth as it is in heaven .  We put our hope and trust in You, the only Righteous God and Your anointed Son, King Jesus.  May the whole earth be filled with Your glory. Amen.
