Sharper Iron — The Gospel in Action: Jesus’ Authority in Word and Deed

Rev. Luke Zimmerman, pastor at Calvary Evangelical Lutheran Church in Mechanicsburg, PA, joins host Rev. Timothy Appel to study Mark 1:21-28.

Jesus’ authority is apparent from the beginning of His public ministry. He teaches in the synagogue at Capernaum, His adopted home base of operation for His Galilean ministry. Jesus did not teach the Word as rabbis quoting other rabbis; He taught the Word as the Author. His authority is on further display as He rebukes a demon. An unclean spirit approaches Jesus, recognizing that Jesus is an enemy to Satan’s reign. In bringing the reign of God, Jesus retakes territory from the demonic usurpers. With a Word, the Holy One of God rebukes the unclean spirit, and the man once possessed is set free. The people are once again amazed, having seen Jesus’ authority in both word and deed. Jesus’ fame spreads as the narrative continues, pushing toward the authority Jesus ultimately shows by giving His life on the cross.

“The Gospel in Action” is a mini-series on Sharper Iron that goes through the Gospel according to St. Mark. The Evangelist hits the ground running with the very first verse of his Gospel account, and he never lets up the pace. As one deed of Jesus comes right after another, always paired with His authoritative Word, St. Mark proclaims the good news that Jesus Christ is the Son of God, revealed conclusively by His death on the cross.

Sharper Iron, hosted by Rev. Timothy Appel, looks at the text of Holy Scripture both in its broad context and its narrow detail, all for the sake of proclaiming Christ crucified and risen for sinners. Two pastors engage with God’s Word to sharpen not only their own faith and knowledge, but the faith and knowledge of all who listen.

Mark 1:21-28

Jesus Heals a Man with an Unclean Spirit

²¹And they went into Capernaum, and immediately on the Sabbath he entered the synagogue and was teaching. ²²And they were astonished at his teaching, for he taught them as one who had authority, and not as the scribes. ²³And immediately there was in their synagogue a man with an unclean spirit. And he cried out, ²⁴“What have you to do with us, Jesus of Nazareth? Have you come to destroy us? I know who you are—the Holy One of God.” ²⁵But Jesus rebuked him, saying, “Be silent, and come out of him!” ²⁶And the unclean spirit, convulsing him and crying out with a loud voice, came out of him. ²⁷And they were all amazed, so that they questioned among themselves, saying, “What is this? A new teaching with authority! He commands even the unclean spirits, and they obey him.” ²⁸And at once his fame spread everywhere throughout all the surrounding region of Galilee.

Rev. Timothy Appel

Although a mathematics degree may not be incredibly helpful to (proudly born-and-raised Texan) Rev. Timothy Appel while hosting Sharper Iron, his love of CFW Walther and the season of Easter will come in handy. His Call is shepherding the flock at Faith Lutheran Church in Godfrey, Illinois, and he’s also husband to wife Kristin and dad to their growing basketball team of children. When he’s not carrying out pastoral duties, you may find him reading “The Lord of the Rings,” snacking on Reese’s peanut butter cups, playing dominoes with his boys, or studying up on Texas history (including Sam Houston, of course).
