Could Satan Sway Jesus Christ?

Jesus once said, "The prince of this world has nothing in Me" (John 14:30). There was nothing in Jesus Christ that could respond sympathetically to anything Satan said, or anything Satan offered. Christ was immune to the devil. This was first due to the fact that Jesus was God the Son, and God cannot sin. Then, second, Jesus' human nature was sinless because it was joined with His divine nature. 

Being a human does not automatically make a person able to sin. The souls of the saints gone on to heaven are all still human, and yet they cannot sin. We don't turn into angels when we die. The resurrected believers who will live and reign during the Millennium will not be able to sin, even though we will still be human beings.  Jesus was fully human, but He could not sin because He had no lusts to which temptation could appeal (James 1:14).

In Jesus' case, Satan's suggestions all dropped to the ground, like frozen sparrows dropping dead out of a winter sky. Jesus, who was perfect in Himself from all eternity past, had perfect faith. This rendered Him immune to evil influencers. Christ also held a perfect knowledge of God's Word (which you would figure, since He as the pre-existent Son of God gave it to the prophets). So Christ could not err in His knowledge of God's will.

The greatness of Jesus' impeccability -- His spiritual purity, and His inability to sin in any sense -- is that it means He is the One on whom we rely for victory over temptation. 

If being human means that someone can sin, then that would mean that Jesus could sin now, since He is still fully human. But Jesus cannot sin now, and could not sin in His days on the earth, because His human nature was perfectly coupled with His divine nature (without either nature melting into the other one, or either one losing its special characteristics).

Christus Victor!  Christ is our Victor over Satan.
