He shall redeem their soul from deceit and violence

… and precious shall their blood be in his sight.  Psalm 72:14

This strong messianic psalm looks forward to the day Messiah will rule over the earth.  Like the prophets, this psalm emphasizes his endless, universal rule, portrays a time of justice for the oppressed and needy, and prosperity for all.  The Day of the Lord will come.  He had come after many prophesies were given in OT.  So, His second coming will also happen to fulfill the many prophesies given in both OT and NT.  He will keep His promise.  He has a good track record for it.
