Passage
and they were all amazed, so as to reason among themselves, saying, `What is this? what new teaching <FI>is<Fi> this? that with authority also the unclean spirits he commandeth, and they obey him!'
and they were all amazed, so as to reason among themselves, saying, `What is this? what new teaching <FI>is<Fi> this? that with authority also the unclean spirits he commandeth, and they obey him!'
Mark 1:25 And Jesus rebuked him, saying, `Be silenced, and come forth out of him,'
Mark 1:26 and the unclean spirit having torn him, and having cried with a great voice, came forth out of him,
Mark 1:27 and they were all amazed, so as to reason among themselves, saying, `What is this? what new teaching <FI>is<Fi> this? that with authority also the unclean spirits he commandeth, and they obey him!'
Mark 1:28 And the fame of him went forth immediately to all the region, round about, of Galilee.
Mark 1:29 And immediately, having come forth out of the synagogue, they went to the house of Simon and Andrew, with James and John,
The verse centers on "Spirit", "amazed", "reason", "themselves", "saying", "teaching", "authority", and "unclean". It is saying that the verse draws attention to "Spirit" and "amazed", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 26's "and the unclean spirit having torn him..." into verse 28's "And the fame of him went forth...", so "Spirit" and "amazed" 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 "Spirit" and "amazed" with trust shaped by these words, not by a vague optimism outside the passage.
