The text explicitly says
Jesus truly became human, grew, obeyed, suffered, prayed, lacked knowledge of the hour, died, and was exalted.

The eternal Son’s genuinely human life
Luke 2:52; Mark 13:32; John 14:28; Philippians 2:5–8; Hebrews 2:14–18
The textual thesis
The eternal Son did not merely wear a human appearance; He truly became human and lived a real human life of growth, dependence, obedience, suffering, and death.
01
The incarnation is real
The Word became flesh
John 1:14 does not say the Word merely appeared in flesh or temporarily operated a human body. The Word became flesh. Hebrews says He shared in flesh and blood and was made like His brothers and sisters in every respect, yet without sin.
Christian belief must therefore preserve both truths: the One who became human already existed, and the humanity He assumed was complete and genuine.
02
A truly human life
Growth, dependence, suffering, and obedience
Jesus grew in wisdom and stature, became tired, hungered, suffered, learned obedience through what He suffered, prayed, and died. These are not defects in the incarnation; they are evidence that His human life was real.
The eternal-Son view does not require pretending Jesus’ human limitations were illusions. It says the divine Son genuinely lived through a human nature and human mode of life.
03
The difficult sayings
The Father is greater—and the Son does not know the hour
John 14:28 speaks within Jesus’ incarnate mission: the Son has humbled Himself, has been sent, and is returning to the Father. ‘The Father is greater than I’ describes that humbled position and mission; it does not erase the passages that place the Son in God’s form and divine identity.
Mark 13:32 must also be allowed to speak without embarrassment: the Son says He does not know the day or hour. The verse confirms a real distinction between Father and Son and the genuineness of Jesus’ human life. It should not be used to deny every text that ascribes divine identity and preexistence to Him.
04
What prayer shows
Not a body speaking to the deity inside it
Jesus’ prayers arise from His real human dependence and from His genuine relationship with the Father. The incarnate Son truly prays, obeys, trusts, and receives from the Father.
John 17:5 and 17:24 locate this same Father–Son relationship before the world existed. The incarnation introduces genuinely human conditions into the Son’s life; it does not begin His personal relationship with the Father.
What the text contributes
Jesus’ human dependence does not disprove eternal Sonship; it shows how completely the eternal Son entered the human condition in order to redeem it.
Keep the conclusion precise
The text naturally implies
His incarnate limitations belong to a genuinely human life and mission, not to the nonexistence of the Son before Bethlehem.
What this passage does not establish by itself
No single difficult saying should be used to cancel the texts that identify the Son as preexistent Creator and divine Lord; the whole witness must be held together.
