So you also outwardly appear righteous to others, but within you are full of hypocrisy and lawlessness.

Purity, inner purity, the image of purity, ceremonial purity have been attempted by many religions in many different ways. Pure of heart in Scripture seems to define it as a single, undivided heart – those who are sincere and not divided in their devotion and commitment to God. It is an inner purity and has external manifestations of the Holy Spirit which is in them. There are pollutants (sin) that pollute the heart. Greed, pride, lust, power, anger, deception, hate, confusion, self-reliance, self-worth, self-deserving, etc….. When these are present and acted upon there is little to no intimacy or relationship with God. A pure at heart person has heard the voice of God through the Gospel of Jesus Christ and humbly surrendered all of this selfishness, repented, committed, believed, trusted, followed, and obeyed Jesus Christ. The purity of heart comes through this alone and not by external actions, though there certainly are external actions that can be clearly seen in those of a pure heart. Being sensitive to Godly, holy, and heavenly spiritual things requires a heart and soul that is pure to things of God and always voiding the worldly and fleshly desires. If you are not conscious of spiritual things then your heart is focused on something else. The greatest motivator of purity comes from a desire to know and understand the grace, mercy, and love of God so that in all we say, think, and do Jesus Christ is honored and glorified. They want to be pure for His honor and glory, not ours.
