1 Corinthians 12:13 mentions “by one Spirit” we were all baptized into one body. What does this mean? It means that Christians came to be baptized into Christ BY the influence of the Holy Spirit. In other words, none of us would have been immersed in water in the name of Jesus Christ except that we listened to what the Spirit commanded. It was not BY my own wisdom or desire. I never would have been baptized in the name of the Lord except I came under the teaching and directing influence of the Holy Spirit. The Spirit tells us the truth about how to come into the body of Christ. The Law of Moses did not tell me to be baptized in the name of Jesus Christ. The faith of Jesus Christ as revealed and directed by the Holy Spirit is the ONLY reason anyone was ever baptized in the name of the Lord Jesus.
Peter was writing his first general letter, it is believed, between 58-62AD and from the book and knowledge of the time there was growing persecution against Christians. Persecution gets tiring and wears one down. Peter reminded these Christians that God “called you out of darkness into His marvelous light” (1 Peter 2:9). It was light in the heart where we sometimes feel overwhelmed with darkness. When we are rejected by others, and we know we did nothing but good and do not deserve the rejection, we have two options: 1) Let their dark behavior and ignorance flood our hearts so that we see nothing else, or 2) we can let “the Light of the world,” Jesus, dominate our thoughts. The darkness is easier to forget when we have someone so wonderful who loves us and thinks we are worth dying for. The “marvelous light” on the inside must not be allowed to go out by letting the darkness of people’s ignorant rejection of you overwhelm the “marvelous light.” It is “marvelous light” regardless of what is happening to you at the hands of ignorant people. Their darkness must not diminish your light. Your light must carry you through the darkness of this world.
