Samson was a man out of control. He strangled a lion but he could not strangle his own lust. He broke the fetters of his foes, but could not break the cords of his sinful desires. He burned the crops of others, but lost his life when burning with flames of anger kindled by a single woman. If so Jesus was sinning when he drove out the money changers.
Anger is a power, an elemental force.
Like all energy it can be used for good or evil. When it is uncontrolled it is destructive. Channeled and directed it has the potential for good. Christians do not lose their emotions at conversion. Act on your anger.
