“You have heard that it was said to your ancestors,You shall not kill; and whoever kills will be liable to judgment.
But I say to you, whoever is angry with his brother
will be liable to judgment,
and whoever says to his brother, Raqa,
will be answerable to the Sanhedrin,
and whoever says, ‘You fool,’ will be liable to fiery Gehenna.
Therefore, if you bring your gift to the altar,
and there recall that your brother
has anything against you,
leave your gift there at the altar,
go first and be reconciled with your brother,
and then come and offer your gift.”
“Sin speaks to the sinner in the depths of his heart.” Psalm 36:1
Sin does not begin with our angry actions. By bearing a grudge, or harboring anger we have already committed sin. Jesus’s disciples knew that they must not kill. He wants them to understand that to follow him, it is not enough not to commit grave sin, our hearts must be pure. We must not think evil thoughts or use evil words or speak unkindness.
It is not easy to be a follower of Christ. We are accountable not only for our deeds, but for our thoughts and intentions as well. When we examine our consciences, we must look deeper than what we have done. We must look also at why we have done something. What are the inclinations of our heart. What are our deepest desires and thoughts, for these too must be pure, good and holy.
