You are already clean because of the word which I have spoken to you. [John 15:3]
The word of Christ has the power to clean us. It is the tool used by God to cleanse our souls. David Guzik wrote “It condemns sin, it inspires holiness, it promotes growth, it reveals power for victory.” When one receives the word of Christ, his heart is purified by it. The next step would be to abide in Christ in order to bring forth fruit.
