Breaking down a compound word into its parts is one of the easiest ways to understand what it means. The word conscience is a compound word made up of the root word science and the prefix con. The prefix con means with while the root word science means knowledge. As is often the case, the built-in dictionary of the Bible helps to solidify this connection, understanding, and definition. In 1 Corinthians 8:7 and 1 Corinthians 8:10, the word conscience is used in conjunction with the mention of knowledge possessed by men. Romans 2:15 makes a similar connection by joining the word conscience with the statement that something is written in the heart. As such, God designed a man’s conscience as an internal tool to place pure and righteous knowledge within an individual that he would otherwise lack.
When a believer meditates upon the things of God, those truths become more firmly planted in the heart. Eventually, the contents of the heart become evident from the words that escape the mouth (Luke 6:45). Therefore, the meditations of our heart will eventually be the words of our conversations. This is exactly the truth conveyed by Asaph in our passage from Psalm 77. He understood that meditation upon the work of God would eventually cause him to talk of God’s doings. It is right for God’s people to speak truth, especially when it concerns testifying to the truth of God’s holy words. Yet, this is not possible unless a believer first hides the words of God in his heart (Psalm 119:11), and one way to do so is through meditation.
