Paul wrote in Galatians 5:9, "A little leaven leavens the whole lump," and Jesus likened the Pharisees teaching to "leaven" because false teaching spreads. The false teaching of lordship salvation has the same type of effect, as it has a negative impact on many other areas of one's Christian life. To use another illustration, lordship salvation lays a faulty foundation from which to build upon; therefore, the lingering effects of this false gospel need to be exposed.
