Hebrews 4:15 For we have not an high priest which cannot be touched with the feeling of our infirmities; but was in all points tempted like as we are, yet without sin.
The phrase “like as we are” wouldn’t mean anything if Jesus wasn’t “like as we are”. God can not be tempted “like as we are”.
There is no way we can understand how Jesus was both God and man at the same time but if He was not “like as we are” without being God He wouldn’t have been tempted “like as we are”.
Just to add to the discussion on the manhood of Jesus. Consider the following.
If during Jesus’ walk on the Earth he was “100% God”:
How could he suffer, shed his blood, or die if he is immortal? (Romans 5:6-8, 8:32, Heb 9:14-18, 27-28, 12:2, 13:12, 20, )
How could he taste death for everyone? (Heb 2:9)
How could he be tempted and relate to our temptations? (Matthew 4, Heb 4:15)
How could he sympathize with our weaknesses? (Heb 2:18, 4:15)
How could he become sin? (Rom 8:3, 2 Cor 5:21)
Why did he need to be anointed by the Holy Spirit to minister to folks? (Isaiah 61, Luke 4:18, Acts 10:38)
Note the name that he most frequently used for himself - Son of Man. This title disappears in the letters to the Church, the Body of Christ.
Note the names that the Holy Spirit inspires Paul to use for him - Last Adam, and Firstborn of many - meaning there would be more like him. (Romans 5:12-19, 1 Cor 15:20-23 & 45, Col 1:15-18, Heb 1:6)
The key verse:
5 Let this mind be in you, which was also in Christ Jesus: 6 Who, being in the form of God, thought it not robbery to be equal with God: 7 But made himself of no reputation, and took upon him the form of a servant, and was made in the likeness of men: 8 And being found in fashion as a man, he humbled himself, and became obedient to death, even the death of the cross. Philippians 2:5-8 Webster
The original Greek really amplifies what Jesus did. He set aside temporarily his divinity to be the lamb of God, perfect example for man. Hence the enemy’s confusion about what he was doing on Earth:
6 We do, however, speak a message of wisdom among the mature, but not the wisdom of this age or of the rulers of this age, who are coming to nothing. 7 No, we declare God’s wisdom, a mystery that has been hidden and that God destined for our glory before time began. 8 None of the rulers of this age understood it, for if they had, they would not have crucified the Lord of glory. 1 Corinthians 2:6-8 NIV
God’s Word became flesh, spoken by Gabriel and believed by Mary. And through the work of the Holy Spirit, the incorruptible seed was placed in Mary’s womb. This was a spiritual process, not physcial - no physical union between God and Mary like in Greek and Roman mythology - satan’s perversions of the Truth.
During a normal pregnancy, no blood is shared between mother and child, so the sin nature of fallen Adam was not in Jesus - remember life is in the blood. (John 1, Lev 17:11) Jesus would operate as man, like Adam before the fall. He set aside his divine nature to be in all ways, our perfect example.

14 Since the children have flesh and blood, he too shared in their humanity so that by his death he might break the power of him who holds the power of death—that is, the devil—15 and free those who all their lives were held in slavery by their fear of death. Hebrews 2:14-15 NIV
17 For this reason he had to be made like them, fully human in every way, in order that he might become a merciful and faithful high priest in service to God, and that he might make atonement for the sins of the people. 18 Because he himself suffered when he was tempted, he is able to help those who are being tempted. Hebrews 2:17-18 NIV
5 In the same way, Christ did not take on himself the glory of becoming a high priest. But God said to him, “You are my Son; today I have become your Father.” 6 And he says in another place, “You are a priest forever, in the order of Melchizedek.” Hebrews 5:5-6 NIV quoting Psalm 2:7 & 110:4 - Consider when this took place - See verse 9 & 10 of Hebrews 5.
3 Without father or mother, without genealogy, without beginning of days or end of life, resembling the Son of God, he remains a priest forever. Hebrews 7:3 - In the context of comparing Jesus to Melchizedek as an Eternal High Priest, it is relevant to this discussion.
3 Or don’t you know that all of us who were baptized into Christ Jesus were baptized into his death? 4 We were therefore buried with him through baptism into death in order that, just as Christ was raised from the dead through the glory of the Father, we too may live a new life. 5 For if we have been united with him in a death like his, we will certainly also be united with him in a resurrection like his. Romans 6:3-5 NIV
