25 But Jesus rebuked him, saying, “Be quiet, and come out of him!” 26 And when the unclean spirit had convulsed him and cried out with a loud voice, he came out of him. 27 Then they were all amazed, so that they questioned among themselves, saying, “What is this? What new doctrine is this? For with authority He commands even the unclean spirits, and they obey Him.” 28 And immediately His fame spread throughout all the region around Galilee (Mark 1:25–28, NKJV).
Why did Jesus work miracles? The answers are in their motive and effect. The motive of compassion is stated repeatedly for His miracles that removed powerfully removed people’s pain and suffering (Mark 1:41; 5:19; 8:2; Matt. 20:33). (It is noteworthy that His compassion also moved Jesus to teach the word of God, Mark 6:34.) The effect of His miracles was to provide evidence that God sent Him and that His teaching is the word of God (Mark 1:27; John 3:2; 5:36; 20:30-31; Acts 2:22). As in today’s passage, the power of His miracles grabbed people’s attention and supported the authority by which He spoke (Mark 1:21-22, 27-28). God does not work miracles through us today (1 Cor. 13:8-10). Instead, the inspired record of first-century miracles shows Jesus is the Christ, and His gospel is God’s word (John 20:30-31; Acts 14:3). Compassion continues to be His disciples’ motive for helping the weak and teaching the gospel to the lost (Luke 10:33-37; Col. 3:12; 1 Pet. 3:8-9; Matt. 9:35-38; Jude 22-23).
