If we set aside the theistic glasses used to define God, and instead look at Jesus of Nazareth as the redefinition of who and what God is; then these apparently hard questions about Jesus will begin to resolve themselves.
The classic theistic characterization of God centers around omnipotence and associated with this is omniscience, immutableness and the inability to suffer and die.
The traditional theistic definition of God cannot allow for Jesus being mistaken about certain facts, and if he were, this disqualifies him as being in some sense divine. Yet, even in the old testament YHWH is described as being unaware of the facts about a certain situation and in some cases repenting (changing his mind) about an intended course of action.
In fact, the tetragrammaton YHWH, typically translated as “I AM that I AM” should be translated “I shall be what I shall be” or become." to better reflect the verbal nature of ancient Hebrew.
The name revealed to Moses describes the essential character of who and what God is. God will become whatever is needed to save, heal and bring the creation to its full potential as the expression of universal life freely given to all. A creation that will be freed from the almighty power of death so that everyone will have the fullness of authentic life with true justice/equitableness for all.
So with the theistic glasses off we can see this:
Jesus is not god (the theistic god); rather God is Jesus, the God defined by who Jesus is and what he has done. Jesus is the presence/face of God revealed in a living person of flesh and blood in the real world of imperfect, changing, suffering and dying living beings.
God in Jesus is becoming what the real world needs God to be: Not God the almighty, but God the powerless; crucified on a Roman cross. So that God can become the all-bountiful one; pouring out unconditionally and unreservedly all that God is to all that there is.
Not God the omniscient, who sees and knows every action and private thought to be recalled on the Day of Judgement to judge and condemn. Not God with a plan micromanaging each event, no matter how great or small. Rather, God with an irrepressible passion to give all that God is to all that there is. To give himself unconditionally to the ever expanding universe.
In Jesus, God knows all things because he empathetically feels all things. When he healed the sick it was not an act of divine omnipotence but of profound empathy. The word usually translated as pity or compassion is splagchnizoma which literally means a movement in the inner most parts.
Karl Barth comments, “The term obviously defies adequate translation. What it means is that the suffering and sin and abandonment and peril of these men not merely went to the heart of Jesus but right into His heart, into Himself, so that their whole plight was now His own, and as such He saw and suffered it far more keenly than they did. Splagchnizoma means that He took their misery upon Himself, taking it away from them and making it His own.” And in return his presence opens the floodgates of God’s life to heal and make whole those damaged/destroyed by disease and death.
So is Jesus ever wrong, is God all knowing? That is not really relevant to what the world needs God to be. Instead, the real God for the real world, does whatever it takes, at God’s expense, to overcome all that harms and threatens the creation.
Jesus is the Truth because his life, death and resurrection reveals the true nature of God. Not God above and over us, but as Emmanuel, with us, and not lording over us.
He is the Way, because he opens the way from God to the creation by removing and overcoming all the powers (including the almighty power of death) that blocks or diverts the free flow of God’s life to all things in the creation.
He is the Life, because he gave up his life at Golgotha, not to pay for sins so that God can forgive us, but rather to take the life of God to the godless and hopeless, and into death itself. So that in the coming transformation of the cosmos, the third singularity, the Life of God will reach even the abyssal depths of nothingness and hell. So that all that was dead will be made alive again and even that which is not yet alive will be enlivened in ways beyond our imagining
