Matthew 15:19

For out of the heart proceed evil thoughts, murders, adulteries, fornications, thefts, false witness, blasphemies:

Matthew 15:19 (KJV)

Context

Jesus spoke these words to the Pharisees and scribes who challenged Him because His disciples did not observe the traditional washing of hands before eating. In response, Jesus turned the discussion from external rituals to the true source of defilement: the human heart. He had just declared that what enters the mouth does not defile a person, but what comes out of the mouth does. This verse lists the evils that proceed from within.

Meaning

The heart, in biblical usage, represents the inner person—the seat of thought, will, and emotion. Jesus identifies seven specific evils that originate there. Each one reveals how sin is not merely a matter of outward behavior but flows from a corrupted inner life.

Evil thoughts are evil reasonings or deliberations, the internal intentions and desires contrary to God’s will. They are the root from which all other sins grow.

Murders refers to taking a life with malicious intent. Jesus traces this act back to the heart, where anger, hatred, and unforgiveness can fester if not dealt with.

Adulteries includes both the physical act of infidelity and the broader concept of unfaithfulness. Jesus points to the heart as the origin of lustful desires and unfaithful intentions.

Fornications denotes sexual activity outside the bounds of marriage. Such behavior springs from impure desires and motivations within the heart.

Thefts involves taking what does not belong to us. This wrongful act emerges from a covetous or greedy heart that desires to possess what rightfully belongs to others.

False witness is lying or bearing false testimony against someone. Jesus highlights that falsehood originates from a deceitful and dishonest heart.

Blasphemies means speaking irreverently or contemptuously about God or sacred things. Such speech arises from a heart that lacks reverence for the divine.

Biblical connections

This list of sins corresponds to violations of the Ten Commandments: murder (sixth commandment), adultery and fornication (seventh), theft (eighth), false witness (ninth), and blasphemy (related to the third). Jesus is not introducing a new ethic but exposing the inward dimension of the Law. The sins He names are outward manifestations of a corrupt heart, affirming that true righteousness requires inner transformation, not merely external compliance.

Application

This verse calls us to examine our hearts honestly. External religious practices, such as ceremonial washings, cannot cleanse the inner person. We must address the root causes of sin within us by seeking God’s forgiveness, repenting, and allowing His grace and Spirit to work in us. As we do, God transforms us from the inside out, leading to righteous actions and attitudes.

Reflection

Jesus’ words remind us that sin is a heart problem before it becomes a behavior problem. The remedy is not simply to modify our actions but to receive a new heart from God. This verse points to our deep need for the cleansing and renewal that only God can provide.
