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.
The passage may appear to directly equate obedience and submission together, but each word conveys a separate and distinct concept. Although today's passage includes both obedience and submission, it is important to recognize that these two words involve separate acts. Earlier studies noted a twofold definition of obedience: first, having an attentive ear, followed by acting upon what has been said. Dividing submission into two parts helps to better understand it too (sub + mission). The prefix sub means under (thus a submarine travels under the water), and the root word mission means to be sent out. Obedience, therefore, emphasizes the act of hearing and doing, while submission emphasizes the act of placing oneself under the authority of another.
