Jesus stated in John 16:25 that he was speaking in figurative language (veiled speech) about the deity of the Father, but promised that a time would come when he would plainly speak about the Father. It is clear that Jesus used veiled speech about his true identity as “God with us” (Matthew 1:23) as a fully complete man who was “made like unto his brethren (just like all men – Hebrews 2:17)” because he had to humbly fulfill his mission on earth as the Lamb of God who would die for humanity's salvation (Philippians 2:8). This explains why Jesus indirectly referenced himself as the Father rather than directly stating that he was the Father.
If Jesus had claimed his divine rights and privileges as God with us as a man, then he would not have been able to fulfil his mission to die for our sins. That is why Jesus used his human titles as the “Son of God” and “Son of Man” to hide his true identity as the Holy Spirit of God who came down from heaven (Luke 1:35; Matthew 1:20) to become one of us in order to save us. This is the precise meaning of Isaiah 45:15-16 which references the Messiah’s millennial reign: “they shall make supplication unto you, saying, Surely God is in you; and there is none else, there is no (other) God. Truly you are a God that hides Himself, O God of Israel, the Saviour.” Thus, it was impossible for the identity of Jesus as the Spirit of God incarnate as a true man to have ever ceased being the omnipresent God who continued fill the heavens and the earth while simultaneously existing as a man on the earth (Jer. 23:24; Malachi 3:6). Therefore, Jesus as a true man on earth had to have had the divine awareness of both his pre-existence in heaven and his continued omnipresence in the heavens as “the only true God (John 17:3)” through revelations that he had received from his Father.
Isaiah 45:14-15 clearly proves that the Messiah is that God who hid His true identity on earth as a man during the first century, but would plainly reveal His true identity as God after His second coming in His millennial reign, “Truly you are a God who hides Himself, O God of Israel, the Saviour (Isaiah 45:15).” Since Jesus was truly the reproduced Essence of Being of the Father’s Person as a true human person (Hebrews 1:3; Heb. 2:17) through his virgin conception and birth, He could have (through His human divine awareness) claimed to have simultaneously existed in heaven and on earth at the same time just as He could say, “before Abraham was I AM (John 8:58).” And such a man could have (through His human divine awareness received by revelation) claimed to have pre-existed as God the Father by claiming to be where he was before (John 6:62). We must understand that Jesus always spoke out of his human consciousness as the Father’s human mode of existence inside the incarnation as a true man, and never out of an alleged divine consciousness which was always outside of the incarnation as the Father (John 5:26 clearly informs us that “the Father has life in himself” outside of the incarnation and that the “Son has life in himself” as a distinct human life inside of the incarnation through the virgin).
Since Jesus is “God with us” as a true man, he used his incarnational titles, “Son of God” and “Son of Man” as incarnational terms for the God who became a man. The title, “Son of man” is clearly an incarnational title, which means the son of mankind via his virgin conception. Therefore, Jesus was able to hide his true divine identity as the only true God who also became a man by consistently using his incarnational titles rather than plainly declaring Himself to be the Father who became a true man to save His people from their sins.
John 16:25 proves that Jesus used “figurative language” or “veiled speech” when speaking of the deity of the Father. This explains why Jesus veiled his true identity by saying, “What then if you see the Son of man ascending to where he was before (John 6:62)?” Jesus clearly pre-existed his birth as the only true God - the Father (John 8:58; John 17:3; 1 John 5:20). If a finite man knew that His true identity was really God who became a human person with a human mind, a human will, and a human spirit, he could have sometimes said (through his human awareness) that he existed in heaven before becoming a man (John 6:62). Since Jesus spoke as a fully complete man on earth with a fully complete human consciousness, it would make sense to believe that He would sometimes reveal that He came forth from the omnipresent Spirit of God and was going to return back to God in order to inherit all things (Heb. 1:4) as God with us as a man (Matthew 1:20-23; Heb. 2:14-17).
John 16:28 states that Jesus came into the world,
“I came forth from the Father and have come INTO THE WORLD; I am leaving the world again and going to the Father.”
Just as John 16:28 says that Jesus came into the world; so does 1 Timothy 6:7 say that “we brought nothing INTO THE WORLD, and we can take nothing out of it.”
The inspired wording of 1 Timothy 6:7 states that “…we BROUGHT NOTHING INTO THE WORLD” is the same thing as Jesus saying, “I … have COME INTO THE WORLD.” Just as Jesus came “INTO THE WORLD” - so God’s elect came “INTO THE WORLD.” Since God’s elect did not literally pre-exist in heaven before coming “INTO THE WORLD,” so Jesus did not literally exist as a Son before he came “INTO THE WORLD.” Therefore, it is clear that those who were predestined in God’s preconception came into the world from the Father because God already “FOREKNEW” His elect in heaven before they actually came into the world (Ephesians 1:4-5; Romans 8:29).
Furthermore, it is nonsensical to believe that Jesus was merely the incarnation of a God Person only in an external shell of human flesh. Both Trinitarian and Oneness theologians confess that God became a real man in the incarnation with a real human nature and will. Thus, both Trinitarian and Oneness believers must confess that Jesus is not God with us as God, but rather, God with us as a true man who could pray and be tempted. For no Trinitarian or Oneness theologian would confess that God was tempted as God. The same should be true with the human prayers, trials, and sufferings of Jesus. Since Numbers 23:19 states that “God is not a man,” it is impossible for God as God to be tempted of evil, nor can God as God pray or intercede to God. Therefore, the incarnation proves that the God of the Hebrew prophets became a true human son with a fully complete human mind and will which was distinct from the divine will of the only true God the Father. This explains both the prayers and the temptations of Jesus.
