The Sinlessness of Jesus is clearly taught in the Bible. In Hebrews we read that Jesus "has been tempted in every way, just as we are - yet was without sin" (Hebrews 4:15). He is also described as "a high priest [who] meets our need - one who is holy, blameless, pure, set apart from sinners, exalted above the heavens" (Hebrews 7:26) and is "unblemished" (Hebrews 9:14). Even Peter, who knew Jesus well, declared that he "committed no sin, and no deceit was found in his mouth" (1 Peter 2:22). The apostle John tells us that "In him is no sin" (1 John 3:5) and Paul confirms for us that Jesus "had no sin" (2 Corinthians 5:21). Even Jesus himself asked those around him, "Can any of you prove me guilty of sin?" (John 8:46).
Sinless yet human
One problem arises from a study of the sinlessness of Jesus. Some have asked, "If Jesus never sinned, was he truly human?" Wayne Grudem writes:
"The key to understanding the duality of Christ's human nature and His sinlessness is understanding that sin, as part of the human condition, is not the normal condition. God did not create us as sinners, but as a result of the fall, sin has marred our lives. Christ's sinlessness is made clear in Scripture, from His 40 days in the desert, where Satan tempted Christ but failed to entice him in to sin, to the time of the beginning of His ministry where "the favor of God was upon Him" (Luke 2:40)."
