28 I came forth from the Father, and am come into the world: again, I leave the world, and go to the Father. 29 His disciples said unto him, Lo, now speakest thou plainly, and speakest no proverb. 30 Now are we sure that thou knowest all things, and needest not that any man should ask thee: by this we believe that thou camest forth from God. (John 16:28-30 KJV)
William Burkitt’s Commentary
Here observe, 1st. A proof of our Saviour’s godhead; he came forth from the Father into the world; He came out from the Father in his incarnation, and came into the world to accomplish the work of our redemption.
Learn hence, that Jesus Christ is true God, equal with the Father: for he was not only sent by him, but came forth from him; I came out from the Father.
Observe, 2. That it pleased Christ, out of love to his people, to leave the Father, and come into the world; not by being separated from the deity, but by obscuring the deity with the veil of our flesh, in order to the finishing the great and glorious work of redemption for us; I came from the Father, and am come into the world.
Observe, 3. That Christ having finished his suffering work here on earth, ascended into heaven, and sent down the Holy Spirit to apply unto his church, the redemption purchased by his blood: Again I leave the world, and go to the Father.
Observe lastly, how the apostles argue from the knowledge of Christ’s omnipotency to a certainty of his divinity: Now are we sure that thou knowest all things; by this we believe thou camest forth from God. The knowledge and experience of Christ’s omnisciency, may and ought fully to confirm us in the belief of his deity; for that attribute of the deity cannot be communicated to any person without the communication of the divine nature.
