All who heard King Benjamin were anxious to serve the Lord as long as they should live, and expressed a desire to enter such an obligation so to do. The first Christian Church in Zarahemla was then established. King Benjamin gave his people a new name because of the agreement they entreated should be made, which thing was the very thing that Benjamin wished them to do. Everyone, except the little children who could not understand, entered this binding covenant, and which, we might say, most of them kept faithfully. The name they were to bear ever afterward was the "children of Christ," by which they would be known as long as they hearkened to His voice and kept His commandments. In giving them this new name King Benjamin said, "Because of the covenant which ye have made ye shall be called the children of Christ, his sons, and his daughters." Perhaps this passage together with the one found in Mosiah 15:1-4, will help us understand why Jesus is called both the Father and the Son.
The word children is frequently used in a figurative sense in the Hebrew vocabulary. Children of Israel were all the descendants of the Patriarch, Jacob. The children of the world are selfish, materialistic persons, while the children of light love the truth and live accordingly. The children of the devil are doing his work, while the children of God love and obey Him. The children of Christ are His faithful followers. (See John 8:36-44).
