This mediator would be Gods right arm, the one who would set at His right hand. Isaiah 63:5 GOD looked for someone to build up the wall, stand in the gap but found no one . Ezekiel 22:30 GOD could not find a righteous man , Romans 3:10 , no human being has ever been righteous. Psalm 143:2 , Romans 3:23 falling short of GODS glory is to sin because GOD DOES NOT SIN, it is GODS nature to not sin. This mediator would have to have this Godly nature, righteousness and love just as GOD Himself. This mediator would have to be the brightness of GODS glory and express image of GODS character or nature of impeccability. Hebrews 1:3 , John 14:9 , John 10:30 , John 1:14 , 2 Corinthians 4:6 , Colossians 1:15 , John 5:23 Since no man qualified for the position of mediator GOD had to create one. This man would be the messiah, the mediator and the son of GOD.
