Is it true? No.
I’ve heard it said that this was so he could do miracles as a man, because if he did them as God, it would mean that we, as humans, couldn’t do them. When Jesus sent out “the twelve” and “the seventy/seventy-two,” they were fully human and did many miracles, as did Paul, enabled by the power and authority that Jesus conferred on them. No mere human would carry that power and authority.
Jesus called his twelve disciples to him and gave them authority to drive out impure spirits and to heal every disease and sickness. These are the names of the twelve apostles: first, Simon (who is called Peter) and his brother Andrew; James son of Zebedee, and his brother John; Philip and Bartholomew; Thomas and Matthew the tax collector; James son of Alphaeus, and Thaddaeus; Simon the Zealot and Judas Iscariot, who betrayed him.
These twelve Jesus sent out with the following instructions: “Do not go among the Gentiles or enter any town of the Samaritans. Go rather to the lost sheep of Israel. As you go, proclaim this message: ‘The kingdom of heaven has come near.’ Heal the sick, raise the dead, cleanse those who have leprosy, drive out demons. Freely you have received; freely give. Matthew 10:1-8
“When you enter a town and are welcomed, eat what is offered to you. Heal the sick who are there and tell them, ‘The kingdom of God has come near to you.’ Luke 10:8,9
The Bible says Jesus was born fully God and fully human—at the same time. The entire time.
For God was pleased to have all his fullness dwell in him, and through him to reconcile to himself all things, whether things on earth or things in heaven, by making peace through his blood, shed on the cross. Colossians 1:19,20
For in Christ all the fullness of the Deity lives in bodily form… Colossians 2:9
When Paul wrote that Jesus “emptied” or “humbled” himself, he didn’t mean Jesus was no longer God, but that he was willing to restrain himself so that he could experience what we experience, and ultimately die for us.
In your relationships with one another, have the same mindset as Christ Jesus: Who, being in very nature God, did not consider equality with God something to be used to his own advantage; rather, he made himself nothing by taking the very nature of a servant, being made in human likeness. And being found in appearance as a man, he humbled himself by becoming obedient to death—even death on a cross! Philippians 2:5-8
