Jehu's Methods are Redundant

Elijah anointed Jehu as king, be he did not turn Israel around. He and his son continued in the sins of Jeroboam. In 2 Kings 17:16, Israel was still worshipping Baal. They eventually went into exile. Jehu’s killings did not bring blessing to Israel.

There are two reasons. Firstly, you cannot beat evil with evil; violence just produces more violence. Jesus rebuked those who wanted to use violence to advance his cause (Luke 9:54-55).

Secondly, guns and bullets kill people, but they cannot change the spirits that are at work in a place. Elijah and Jehu were unable to bind the spirits that controlled Israel.

Post Jesus, that has changed. Spiritual warfare is now more effective than physical warfare, unless you belong to a nation that trusts in war, and are weak in dealing with spirits of hatred and violence. Using Old Testament methods is pointless now we have the new covenant.
