In Mark 3:1–6, Jesus was angry because the Pharisees were hard of heart. How could Jesus, the perfect man, experience anger?
In His humanity, Jesus was conceived of the Holy Spirit (Matt. 1:20–21), born of the virgin, Mary (Matt. 1:22–25). The Lord Jesus knew not sin (2 Cor. 5:21), committed no sin (1 Peter 2:22), and in Him there is no sin (1 John 3:5). Since Jesus is sinless, it is obvious that anger can be holy and pure and free from sin. The Lord’s anger in Mark 3 was neither a loss of self-control nor the rage of a powerless person, but the perfect demonstration of His holy nature and heart toward sin.
