When Jesus spoke of how nothing by entering the body defiles the body, He went on to teach us that it is what proceeds from the heart that defiles the body, murders, adultery, covetness, etc. In so doing He emphasizes obeying the law.
It is not the hearers of the Word who are justified, it is the doers of the Word. ¨Start by hearing our Savior, then obey Him. It is its own reward.
If some will not hear truth from one who is alive, they will not hear even from one who is risen from the dead.
