Psalm 41:12 As for me, You uphold me in my integrity, And set me before Your face forever.
God upheld Jesus because of many things; what set Him apart from other humans was the fact He was without sin.
His ‘reward’ for being perfect is to have a seat with God in Heaven, to be able to see Him face to face and enjoy eternity in Heaven.
Jesus wants us to be able to join Him in Heaven but our sin is holding us back; admitting our sin to Him and asking for forgiveness will allow us to join Him for eternity!
