Thanks for this most basic, but most important question. Here are some quotes from The Urantia Book that at least partially answer your question:
Jesus is the spiritual lens in human likeness which makes visible to the material creature Him who is invisible. (169:4.13)
Jesus is truly a savior in the sense that his life and death do win men over to goodness and righteous survival. Jesus loves men so much that his love awakens the response of love in the human heart. (188:5.2)
But when Jesus had finished his earth life, this name of the Father had been so revealed that the Master, who was the Father incarnate, could truly say:
I am the bread of life.
I am the living water.
I am the light of the world.
I am the desire of all ages.
I am the open door to eternal salvation.
I am the reality of endless life.
I am the good shepherd.
I am the pathway of infinite perfection.
I am the resurrection and the life.
I am the secret of eternal survival.
I am the way, the truth, and the life.
I am the infinite Father of my finite children.
I am the true vine; you are the branches.
I am the hope of all who know the living truth.
I am the living bridge from one world to another.
I am the living link between time and eternity.
Thus did Jesus enlarge the living revelation of the name of God God's Will to all generations. As divine love reveals the nature of God, eternal truth discloses his name in ever-enlarging proportions. (182:1.10)
