Hi Slim,
The fact that the NT is centered on Jesus Christ takes nothing away but only adds to the Father's glory.
And he is before all things, and in him all things hold together. And he is the head of the body, the church. He is the beginning, the firstborn from the dead, that in everything he might be preeminent.
It is not a matter of where we put the emphasis...but where God puts the emphasis.
Acts 1:8 — Jesus says his followers will be his witnesses in all the earth
Acts 2:32 — witnesses to the fact that God resurrected Jesus
Acts 5:32 — witnesses to the fact that God raised up Jesus and exalted him to his right hand
Acts 10:39 — witnesses to the things Jesus did by God's power
Acts 13:31 — witnesses of the resurrected Jesus
And it is where Jesus puts the emphasis
1. Jesus is the Bread of Life
“Then Jesus declared, ‘I am the bread of life. He who comes to me will never go hungry, and he who believes in me will never be thirsty.’” (John 6:35)
“Most assuredly, I say to you, Moses did not give you the bread from heaven, but My Father gives you the true bread from heaven. For the bread of God is He who comes down from heaven and gives life to the world.” (John 6:32-33)
2. Jesus is the Light of the World
“When Jesus spoke again to the people, he said, ‘I am the light of the world. Whoever follows me will never walk in darkness, but will have the light of life.’” (John 8:12)
3. Jesus is the Door
“I am the door. If anyone enters by Me, he will be saved, and will go in and out and find pasture.” (John 10:9) “All who ever came before Me are thieves and robbers, but the sheep did not hear them” (John 10:8).
Others may come and try to declare that they are the way to life, but they are “thieves and robbers”; Jesus is the only true way (see point six). There is no other door to eternal life except through Him.
4. Jesus is the Good Shepherd
“I am the good shepherd. The good shepherd lays down his life for the sheep.” (John 10:11)
5. Jesus is the Resurrection and the Life
Jesus said to her, “I am the resurrection and the life. He who believes in me will live, even though he dies; and whoever lives and believes in me will never die.” (John 11:25-26)
6. Jesus is the Way, the Truth, and the Life
Jesus answered, “I am the way and the truth and the life. No one comes to the Father except through me.” (John 14:6) “And you shall know the truth, and the truth shall make you free.” (John 8:32)
7. Jesus is the Vine
“I am the vine; you are the branches. If a man remains in me and I in him, he will bear much fruit; apart from me you can do nothing.” (John 15:5)
I believe that not only is the New Testament Christocentric , but so is the Old Testament.
