He who has the bride is the bridegroom; but the friend of the bridegroom, who stands and hears him, rejoices greatly because of the bridegroom's voice. This, my joy, therefore is made full.
When John the Baptist spoke these words the church was an unknown entity in God’s plan, so it is unlikely that it was in his mind. However the original readers of this Gospel were probably familiar with the Apostle Paul’s revelations concerning the church being the bride of Christ (e.g., 2 Corinthians 11:2; Ephesians 5:25-27; Ephesians 5:32). Israel had spurned her bridegroom when He came for her, and consequently He had taken a different bride for Himself. John’s joy was complete or full (Gr. pleroun) because he knew that he was fulfilling his role faithfully. Jesus’ increasing popularity filled John’s disciples with resentment, but it filled John with joy.
