As long as you keep your mouth closed, I told myself, you won’t be doing anything wrong. I’d been outwardly holding back my anger towards a colleague after misinterpreting things she’d said. Since we had to see each other every day, I decided to limit communication to only what was necessary (and retaliate with my silent treatment). How could a quiet demeanour be wrong?
Jesus said that sin begins in the heart (Matthew 15:18−20). My silence may have fooled people into thinking all was well, but it wasn’t fooling God. He knew I was hiding a heart filled with anger. I was like the Pharisees who honoured God with their lips, but their hearts were far from Him (v. 8). Even though my outward appearance didn’t show my true feelings, the bitterness was festering inside me. The joy and closeness I’d always felt with my heavenly Father were gone. Nurturing and hiding sin does that.
By God’s grace, I told my colleague how I was feeling and apologised. She graciously forgave me and, eventually, we became good friends. “Out of the heart come evil thoughts” (v. 19), Jesus says. The state of our heart matters because evil residing there can overflow into our lives. Both our exterior and interior matter.

REFLECT & PRAY
Jesus said that the sin in our heart defiles us. What “evil thoughts” might be defiling your heart? How can you pray regarding this matter?
Loving God, please forgive me for the sins I’ve been nurturing in my heart. I want my heart to be pleasing in Your sight. Please help me to change.
SCRIPTURE INSIGHT
When Jesus quoted Isaiah in Matthew 15:8-9, it was from a passage in which God, through the prophet, confronted the people of Jerusalem over their self-righteous religious practices (Isaiah 29:13). In that day, the people claimed to know God, but their actions proved their hearts were stone-cold. In the Messiah’s day, He directed Isaiah’s accusation specifically at the Pharisees, who were guilty of the same sin. The Pharisees had just accused Jesus of His failure to wash His hands before eating. Mark’s parallel account about this scene expands on the Pharisees’ unhelpful tradition (see Mark 7:3-4). There was nothing wrong with the washing of one’s hands prior to eating. But the Pharisees had made this a requirement, elevating “human rules” to the status of God-ordained law (Matthew 15:9).
