When he preaches repentance, John the Baptist points us to Christ Jesus. John was sent by God “as a witness, to bear witness about the Light, that all might believe through him” (John 1:7). He baptizes with water in order to “make straight the way of the Lord,” who shall redeem His people from their sins (John 1:23). That Lord Jesus “who comes after” John now stands among us and makes Himself known to us (John 1:26–27). He has been anointed by the Holy Spirit “to bring good news to the poor” and “to bind up the brokenhearted” (Is. 61:1).
By the washing of the water with His Word and Spirit, He clothes His Church with “the garments of salvation” and adorns her with His own righteousness “as a bride adorns herself with her jewels” (Is. 61:10). Therefore, we “rejoice always” in the Lord, “pray without ceasing,” and “give thanks in all circumstances” (1 Thess. 5:16–18). For “the God of peace,” who has called you by the Gospel, will surely “sanctify you completely,” so that “your whole spirit and soul and body” will “be kept blameless at the coming of our Lord Jesus Christ” (1 Thess. 5:23–24).
