What does the Bible say about the impeccability of Christ?

The impeccability of Christ is firmly supported by Scripture, which repeatedly affirms His sinlessness. In 1 Peter 2:22, it is declared, 'He committed no sin, neither was deceit found in His mouth.' Similarly, 1 John 3:5 states, 'In Him is no sin.' Additionally, Hebrews 4:15 reveals that Jesus, though tempted in every way, was 'without sin.' This underscores that not only did He not sin, but He was incapable of yielding to sin, being the God-man united in one person from the moment of His conception.

His impeccability is further evidenced by His divine attributes of omnipotence and immutability. Revelation 1:8 portrays Christ as 'the Almighty,' meaning He cannot be overpowered by any temptation or sin. The immutability of Christ, expressed in Hebrews 13:8, assures us that His nature is unchanged, thus making it impossible for Him to sin. Furthermore, since Christ's human nature was inseparably united with His divine person, it never existed in a probationary state and therefore was incapable of sinning, which is a stark contrast to Adam and the angels who fell from grace.
