1Let’s fear therefore, lest perhaps anyone of you should seem to have come short of a promise of entering into his rest. 2For indeed we have had good news preached to us, even as they also did, but the word they heard didn’t profit them, because it wasn’t mixed with faith by those who heard. 3For we who have believed do enter into that rest, even as he has said, “As I swore in my wrath, they will not enter into my rest;” although the works were finished from the foundation of the world. 4For he has said this somewhere about the seventh day, “God rested on the seventh day from all his works;” 5and in this place again, “They will not enter into my rest.”
6Seeing therefore it remains that some should enter into it, and they to whom the good news was preached before failed to enter in because of disobedience, 7he again defines a certain day, “today”, saying through David so long a time afterward (just as has been said),
“Today if you will hear his voice,
don’t harden your hearts.”
8For if Joshua had given them rest, he would not have spoken afterward of another day. 9There remains therefore a Sabbath rest for the people of God. 10For he who has entered into his rest has himself also rested from his works, as God did from his. 11Let’s therefore give diligence to enter into that rest, lest anyone fall after the same example of disobedience. 12For the word of God is living and active, and sharper than any two-edged sword, piercing even to the dividing of soul and spirit, of both joints and marrow, and is able to discern the thoughts and intentions of the heart. 13There is no creature that is hidden from his sight, but all things are naked and laid open before the eyes of him to whom we must give an account.
14Having then a great high priest who has passed through the heavens, Jesus, the Son of God, let’s hold tightly to our confession. 15For we don’t have a high priest who can’t be touched with the feeling of our infirmities, but one who has been in all points tempted like we are, yet without sin. 16Let’s therefore draw near with boldness to the throne of grace, that we may receive mercy and may find grace for help in time of need.
Jesus Christ was fully God and fully human and these facts raise the question of the potential for sin in the life of Jesus. Since Jesus was fully human, does that mean there was a sinful nature? The issue of the possibility of Jesus Christ yielding to temptation and sinning deals with the theological terms peccability and impeccability and come from the Latin word peccare, “to sin.” If one holds to the peccability of Jesus, then their position is that Christ could sin, but didn’t do so. If one argues for impeccability then the position is that Christ could not sin. The discussion is one regarding the phrases “able not to sin” and “not able to sin.”
In accordance with the teaching of Scripture, both views acknowledge that Christ’s temptations were real (Heb 4:15), Christ experienced struggle (Matt 26:36-46), and Christ did not sin (2 Cor 5:21; Heb 7:26; James 5:6; 1 Pet 2:22, 3:18; 1 John 3:5). Those who argue that Christ could sin contend that it is a logical deduction that if and since Christ was tempted, He could have sinned. To say that He could not sin is to say the temptations were not real and that ultimately He cannot truly sympathize with humanity. They also contend that if the possibility of sinning did not exist then Jesus did not have freedom of the will.
In response, the fact that Jesus could be and was tempted does not mean that He was susceptible to sin. By analogy, we note that just because an army can be attacked, that does not mean that the army can be conquered. Because of Christ’s unique nature (without a sinful nature), that which applies to us (temptation and susceptibility) does not necessarily apply to Christ. Christ can understand and sympathize with human suffering and temptation because although His temptations were not always exactly parallel to those that we experience, His human nature was tried. The temptations of Christ were in every way like ours except that they did not originate in Himself; He was tempted from without, not from within. Jesus Christ manifested His free will by not sinning. Although tempted like us, Jesus never sinned. Because Jesus uniquely had two natures, fully divine and fully human, those natures existed and functioned simultaneously. Had his human nature existed independently then theoretically Jesus could have sinned. However, it did not exist as such. Both the human and divine natures existed fully in Jesus from the moment of conception. Had Jesus sinned, the act would have involved both natures and Jesus would then not have been truly God. Our conclusion must be therefore that it was not possible for Jesus to sin. The temptations of Jesus were real because He did not give in to them. We must always remember that when thinking about issues such as these we are dealing with Jesus as fully God and fully human—something that never has been and never will be true of anyone else. It is also something that we are unable to fully comprehend. We must affirm the teachings of Scripture and do so knowing that our understanding of them is true but incomplete.
