This is a prayer prayed with “plural” language. David is praying not only for himself but also for all of God’s people. A lot of the prophets of old prayed in this manner… we should probably be praying in a similar manner as well.
God is building a spiritual kingdom. God is building his church. We do know that God is building this kingdom from every tribe and every nation. We do not live before God as only an individual.
We should not just pray for ourselves… and not just for our families… and not only the local church… we should also pray for “all of God’s people.”
Justice demands that all sinners die. God in His mercy desires that each sinner turns to him and pleads for his mercy. God looks at us with mercy and will cover our sin. He will revive us again with his love.
