You Are Prepared through Repentance for the Coming of the Lord

“The gospel of Jesus Christ, the Son of God” (Mark 1:1) begins when John the Baptist appears and comes “proclaiming a baptism of repentance for the forgiveness of sins” (Mark 1:4). As the prophet Isaiah had written, John is the messenger of the Lord, sent before His face to prepare His way. To this day, the ministry of the forerunner continues in the preaching of the Law and the Gospel and in the Sacrament of Holy Baptism. By these ways and means, “the glory of the Lord shall be revealed, and all flesh shall see it together” (Is. 40:5), and the Good Shepherd “will gather the lambs in his arms” (Is. 40:11). He speaks “tenderly to Jerusalem,” and He comforts His people by pardoning their iniquity (Is. 40:1–2). What is more, He promises “new heavens and a new earth in which righteousness dwells” (2 Peter 3:13). Repent, therefore, and humble yourself as you wait for His coming in peace (2 Peter 3:14), because He “is patient toward you, not wishing that any should perish, but that all should reach repentance” (2 Peter 3:9).
