“get rid of all moral filth and the evil that is so prevalent and humbly accept the word planted in you, which can save you.” (James 1:21)
If you are a true Christian you have the Word of God “planted” in you (see Mark 4:14-20). It is not only something you hear and read, but it lives inside you. This word saves you and enables you to “get rid of all moral filth and evil.” You are incapable of doing this if you do not have the Word abiding inside you. This is because the power to change in a meaningful way only comes through the power of God, not through human effort.
