“Therefore whatever you have said in the dark shall be heard in the light, and what you have whispered in private rooms shall be proclaimed on the housetops” (v3). Jesus told his disciples to “beware” of the hypocrisy of the Pharisees, who thought they could hide their ungodly attitudes, words, or actions behind closed doors, while looking righteous in public. Jesus said that instead of fearing being caught by the authorities or religious leaders, we should realize that we will have to answer to God Himself (v5).
“Why, even the hairs of your head are all numbered” (v7). Nothing can be hidden from God, but if our hearts are open and repentant, we receive His attention as grace.
