Mark 7

v1-23: “We become repugnant in the sight of God by what comes out of us.”  It is our thoughts, attitudes, words, actions that are corrupt, which defile us and make us unfit for fellowship with God, and their origin is in our hearts.  Our great concern must be to have our hearts washed clean of this wickedness.

v24-30: "The greatest blessing we can ask of Christ for our children is that he would break the power of Satan, that is, the power of sin, in their souls, and especially that he would drive out the evil spirit, so that they may be temples of the Holy Spirit and he may live in them."

v31-37: The healing of the deaf and mute man should remind us to be thankful to God if we hear and speak.  If we can hear that means we are able to hear the word of God.  If we can speak that means we are able to speak in praise to God.
