Passage
They were astonished at his teaching, for he taught them as having authority, and not as the scribes.
They were astonished at his teaching, for he taught them as having authority, and not as the scribes.
Mark 1:20 Immediately he called them, and they left their father, Zebedee, in the boat with the hired servants, and went after him.
Mark 1:21 They went into Capernaum, and immediately on the Sabbath day he entered into the synagogue and taught.
Mark 1:22 They were astonished at his teaching, for he taught them as having authority, and not as the scribes.
Mark 1:23 Immediately there was in their synagogue a man with an unclean spirit, and he cried out,
Mark 1:24 saying, “Ha! What do we have to do with you, Jesus, you Nazarene? Have you come to destroy us? I know you who you are: the Holy One of God!”
The verse centers on "astonished", "teaching", "taught", "having", "authority", and "scribes". It is saying that the verse draws attention to "astonished" and "teaching", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 21's "They went into Capernaum and immediately on..." into verse 23's "Immediately there was in their synagogue a...", so "astonished" and "teaching" belong inside that flow. In Mark context, the local focus is Christ, faith, and discipleship.
A plain takeaway is to answer the verse's own emphasis on "astonished" and "teaching" with trust shaped by these words, not by a vague optimism outside the passage.
