Mark 1:21-34
As One with Authority
It was a common practice for visiting teachers to be invited to read the Scripture and/or speak, a custom from which Paul as well as Jesus benefited. That Jesus was invited to speak indicates he had already established a reputation as a teacher and that this was not one of the first events in his ministry. Jesus was recognized as a teacher even by his opponents (cf. 12:19), although there is no evidence that he had received any formal training. Certainly he was not a typical rabbi.
In v. 24 the demon acknowledged the true identity of Jesus (cf. v. 34)—something the disciples were slow to do. In fact, only at the crucifixion did a human being confess Jesus as the Son of God, and he was not one of the disciples (15:39).
Home Base = Peter’s House
The disciples are looking for Jesus
Everywhere else in Mark, however, the Greek verb, which is not the same as in v. 36, translated “looking for” means to seek with evil or inappropriate intention. Mark recognized that the acclaim of the crowd was not good.
