Luke explains why the people of Capernaum were amazed, “because his message had authority.” Mark adds that the teachers of the law did not portray this authority when they spoke (Mark 1:22)
Luke comments that the people of Capernaum were “amazed at his teaching.” They were thrilled and delighted. They did not expect a common self-educated person to know the word of God so well. Jesus said later in his ministry that he would send the Holy Spirit to those who believe in him. He said that the Holy Spirit will “teach you all things and will remind you of everything I have said to you. … he will testify about me.” (John 14:26)
The Holy Spirit reminds us of Jesus and his teachings (John 14:16, 26, 16:7). Jesus also told his disciples to not call anyone teacher (Rabbi in Hebrew), nor father, because there is only one teacher and he is the Christ, and our teacher now the Holy Spirit (Matthew 23:8-10). For this reason, we should study the Bible and pray for the Holy Spirit to teach us so that we can give a message of authority.
