Jesus came not to abolish the law, but to fulfill every jot and tittle. The blessed members of His kingdom are to be the salt of the earth, stand like a city on a hill, and shine as the light of the world in love and good works.

If we are going to come to Christ and thrive in His kingdom, we have to deal with our anger at its root.
