Jesus cleans from the inside out.
God sees into our hearts and he knows if we love him and others sincerely. With the Grace of God we too can be like God and love all we meet, even those who are our enemies. The love of God is the most powerful reality in the whole universe. Love God and love others.
Matthew 23: 23-26
23 Woe to you scribes and Pharisees, hypocrites; because you tithe mint, and anise, and cummin, and have left the weightier things of the law; judgment, and mercy, and faith. These things you ought to have done, and not to leave those undone.
24 Blind guides, who strain out a gnat, and swallow a camel.
25 Woe to you scribes and Pharisees, hypocrites; because you make clean the outside of the cup and of the dish, but within you are full of rapine and uncleanness.
26 Thou blind Pharisee, first make clean the inside of the cup and of the dish, that the outside may become clean.
