Wes, I found this article, but unfortunately I don't know who wrote it, it seems pretty solid. You wrote that Jesus was tempted like us, yet without sinning, which I agree with, but how does one who does not have a sinful inclination ("Original Sin")like our Savior, be tempted like us?

"Although Christ was repeatedly "tempted" during His ministry (cf. Luke 4:13, 22:28; Mark 8:11), His great temptation (Matt. 4:1 and parallels) is the focus of this study unit. His temptation was a testing for demonstration of His purity and sinlessness (Heb. 4:15) without any possibility of enticement to evil (James 1:13).

PECCABILITY

The view that Christ could have sinned is termed peccability (Lat. potuit non peccare, "able not to sin,") while the view that Christ could not have sinned is designated impeccability (Lat. non potuit peccare, "not able to sin"). Among evangelicals the issue is not whether or not Christ sinned; all evangelicals would deny that Christ actually sinned. The question in the debate is whether or not Christ could have sinned. Generally (not always), Calvinists believe that Christ could not have sinned, whereas Arminians generally believe that Christ could have sinned but did not.

Those who hold to the peccability of Christ do so on the basis of Hebrews 4:15: He "has been tempted in all things as we are, yet without sin." If the temptation was genuine then Christ had to be able to sin, otherwise the temptation was not a genuine temptation. Charles Hodge, a Reformed theologian, is perhaps the best representative of this view. He states:

"If He was a true man He must have been capable of sinning. That He did not sin under the greatest provocation; that when He was reviled He blessed; when He suffered He threatened not; that He was dumb, as a sheep before its shearers, is held up to us as an example. Temptation implies the possibility of sin. If from the constitution of his person it was impossible for Christ to sin, then his temptation was unreal and without effect, and He cannot sympathize with his people."

The radio and written ministries of M. R. DeHaan and Richard DeHaan also teach the peccability of Christ.
The supposed strength of this view is that it alone identifies Christ with humanity in His temptations—they were real temptations. The weaknesses of this view are that it does not sufficiently consider Christ in His Person as God as well as man. Additionally, the word temptation (Gk. peirazo) is also used of God the Father (Acts 15:10; 1 Cor. 10:9; Heb. 3:9) and the Holy Spirit (Acts 5:9). It is unlikely that anyone would say the Father or the Holy Spirit could have sinned. The conclusion is that temptation does not demand the ability to sin. The people genuinely tempted God the Father and the Holy Spirit, but there was no likelihood of those Persons of the Trinity sinning.

IMPECCABILITY

Those who hold to impeccability suggest Christ's temptation by Satan was genuine, but it was impossible for Christ to sin. Several introductory observations should be noted.

Observations.

The purpose of the temptation was not to see if Christ could sin, but to show that He could not sin. The temptation came at a critical time: the beginning of Christ's public ministry. The temptation was designed to show the nation what a unique Savior she had: the impeccable Son of God. It is also noteworthy that it was not Satan who initiated the temptation but the Holy Spirit (Matt. 4:1). If Christ could have sinned, then the Holy Spirit solicited Christ to sin, but that is something God does not do (James 1:13).

Christ's peccability could relate only to His human nature; His divine nature was impeccable. Although Christ had two natures, He was nonetheless one Person and could not divorce Himself of His deity. Wherever He went, the divine nature was present. If the two natures could be separated then it could be said that He could sin in His humanity, but because the human and divine natures cannot be separated from the Person of Christ, and since the divine nature cannot sin, it must be affirmed that Christ could not have sinned.

Evidence.

The evidence for the impeccability of Christ is set forth by William Shedd and others in the following way.

(1) The immutability of Christ (Heb. 13:8). Christ is unchangeable and therefore could not sin. If Christ could have sinned while on earth, then He could sin now because of His immutability. If He could have sinned on earth, what assurance is there that He will not sin now?

(2) The omnipotence of Christ (Matt. 28:18). Christ was omnipotent and therefore could not sin. Weakness is implied where sin is possible, yet there was no weakness of any kind in Christ. How could He be omnipotent and still be able to sin?

(3) The omniscience of Christ (John 2:25). Christ was omniscient and therefore could not sin. Sin depends on ignorance in order that the sinner may be deceived, but Christ could not be deceived because He knows all things, including the hypothetical (Matt. 11:21). If Christ could have sinned then He really did not know what would happen if He would sin.

(4) The deity of Christ. Christ is not only man but also God. If He were only a man then He could have sinned, but God cannot sin and in a union of the two natures, the human nature submits to the divine nature (otherwise the finite is stronger than the infinite). United in the one Person of Christ are the two natures, humanity and deity; because Christ is also deity He could not sin.

(5) The nature of temptation (James 1:14-15). The temptation that came to Christ was from without. However, for sin to take place, there must be an inner response to the outward temptation. Since Jesus did not possess a sin nature, there was nothing within Him to respond to the temptation. People sin because there is an inner response to the outer temptation.

(6) The will of Christ. In moral decisions, Christ could have only one will: to do the will of His Father; in moral decisions the human will was subservient to the divine will. If Christ could have sinned then His human will would have been stronger than the divine will.

(7) The authority of Christ (John 10:18). In His deity, Christ had complete authority over His humanity. For example, no one could take the life of Christ except He would lay it down willingly (John 10:18). If Christ had authority over life and death, He certainly had authority over sin; if He could withhold death at will, He could also withhold sin at will."
