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.
We have already learned that our joy is to be found in the Lord and this joy is a special gift from above. With this truth foundational to our study, what are some things that we can do as believers that will bring us lasting joy? Far too many people think joy surfaces once the stresses of life cease or at least begin to diminish. Yet, the Bible teaches that joy can be found only in faithfully serving the Lord. Today's verse reveals that the disciples found joy through what God had done in and through them! Considering a few more scriptural examples of joy should help to solidify our mindset concerning this subject. The Bible records great joy as the people of God willingly sacrificed to the Lord (1 Chronicles 29:17). Proverbs 21:15 reveals that “It is joy to the just to do judgment.” The book of Luke tells us that there is joy in heaven when one sinner repents (Luke 15:7). From these and other examples, we know that true joy will be found when we willingly serve the Lord God, but never in the things of this world.
