James 1:21 Wherefore lay apart all filthiness and superfluity of naughtiness, and receive with meekness the engrafted word, which is able to save your souls.
God promises us that when you receive the Word of God into you heart it will save your soul. The soul (the self: the mind, will, and emotions) will be saved from sin, death, and the devil when we repent and believe the Gospel. The Holy Spirit moves us to desire to repent of sin and forsake filthiness and naughtiness, and He plants faith in the soul through the Gospel when it is read or heard. We receive the engrafted word with meekness, humility, and simple trust in Christ.
What happens when we hear the Law is that we are willing to give up Sin and Self, Pride and Unbelief, Filthiness and Naughtiness; and when we hear the Gospel we are willing to replace it all with the life of God, who is for us Righteousness and Goodness, Forgiveness and Grace, Love and Good works. Not a bad deal!
This event (repentance and faith) needs to happen in us, in the soul, every day. It is the daily spiritual bread that builds us up and keeps us alive. Let the Word be grafted in to the soul by whatever means. It is able to save you from death and disaster.
