Jesus was tempted just like every other man. "In asmuch then as the children have partaken of flesh and blood, He (Jesus) Himself likewise shared in the same, that through death He might destroy him who had the power of death, that is the devil....Therefore in all things He had to make like His brethren........" -- Hebrews 2:14, 7-18
Being in the flesh (The Son of Man), Jesus faced temptations just like every person, "For we do not have a High Priest who cannot sympathize with our weaknesses, but was in all points tempted as we are, yet without sin." -- Heb. 4:15
Sin is the breaking of God's law (1 John 3:4). The potential for sin is always there. Temptation is the enticement to break God's law (James 1:13-16). You cannot be tempted by something that you are not capable of doing, Jesus had the choice to break God's law but constantly chose not to sin but to do the will of His Father (God.....i.e, as the Son of God).....unlike the rest of us who are tempted and often are subdued by sins enticements. His physical life while on earth demonstrates that mortal man is capable of living a sin free life. And by not sinning He became the only "PERFECT" sacrificial lamb of God in order to free mankind from the bondage and wages of sin......eternal death of both the spirit/soul and flesh, permanently separated from God. (1 Peter 1:18-19).
As explained with no ambiguity whatsoever, "Let this mind be in you which was also in Christ Jesus, who, being in the form of God, did not consider it robbery to be equal with God, but made Himself of no reputation, taking the form of a bondservant, and coming in the likeness of men. And being found in appearance as a man, He humbled Himself and became obedient to the point of death, even the death of the cross." -- Phil. 2:5-8.
"For there is one God, and one Mediator between God and man, the man Christ Jesus." -- 1 Tim. 2-5
"But now Christ has risen from the dead, and has become the firstfruits of those who have fallen asleep (dead). For since by man came death (The sin of Adam), by Man (Christ Jesus) also came the resurrection of the dead." -- 1 Cor. 15:20-21
