The purpose of this essay is to show Jesus is strong enough to save us. This is done by #1 demonstrating His temptations were from outside Himself testifying He was not a sinner; #2 His righteous supremacy and #3 His work is the evidence He is more than able to save.
#1 Jesus was tempted from outside
Jesus was tempted significantly twice by Satan: in the desert (Matt 4:1-11; Luke 4:1-13) and in the Garden (Matt 26:36-46). His temptation, unlike ours, came from without. Since He was not a sinner by nature He wasn’t tempted to sin from within His being. The great weight of temptation was the sins of the world (1 Peter 2:24) not His own sins (Heb 9:12).
Only as God could He possibly accomplish this work which is the point of His being sent. He came to ‘seek and save the lost’ (Luke 19:10) which includes atoning for our sins.
#2 His supremacy
The point here is the supremacy of Christ who was alone able to atone for our sins. He conquered all powers and principalities that rule over us (Col 2:15) demonstrating His supremacy and simultaneously atoned for our sin (Col 2:13-14) signifying His superiority over the grave.
When evangelists call sinners, men dead in their sins (Ephesians 2:1) to repent and believe in Jesus Christ for the forgiveness of their sins and reconciliation with God, this is called salvation, the sinner must have faith or confidence that Jesus Christ can do what the evangelists says He can do.
Thus part of this necessary confidence comes from knowing who Jesus Christ is and one of those facts is that He was born into this world like all of us but His Father is God meaning He is the Son of God and therefore born without sin.
Man is born a sinner and his temptation comes from within. See James 1:13-15: Let no one say when he is tempted, “I am being tempted by God”; for God cannot be tempted by evil, and He Himself does not tempt anyone. But each one is tempted when he is carried away and enticed by his own lust. Then when lust has conceived, it gives birth to sin; and when sin is accomplished, it brings forth death.”
#3 His work is evidence He is more than able to save
Again, evangelists call sinners to repent and believe in the sinless One, the Holy One of God, (Mark 1:24; Luke 4:34; John 6:69; Acts 2:27; Acts 13:15) to bring salvation to their soul. Can He be trusted to do what the evangelist is saying He can do?
As the Son of God without sin He is strong enough to endure and overcome the temptations of Satan. This work, plus His going to the cross and being resurrected, demonstrate He is trustworthy as a Savior of the sinner’s soul (Hebrews 7:25).
