Here is the oneness that exists between the Father and the Son—a oneness in redemption. Yet since redemption is a divine act, here we have the testimony to the deity of Christ, for no apostle, no prophet, can be said to be “one” with the Father in saving believers in the way announced here. No mere creature can have this kind of perfect unity of purpose and action. No, Jesus Christ must be perfect deity to be able to say of himself in reference to redemption, “I and the Father are one.”
