Passage
being grieved because of their teaching the people, and preaching in Jesus the rising again out of the dead--
being grieved because of their teaching the people, and preaching in Jesus the rising again out of the dead--
Acts 4:1 And as they are speaking unto the people, there came to them the priests, and the magistrate of the temple, and the Sadducees--
Acts 4:2 being grieved because of their teaching the people, and preaching in Jesus the rising again out of the dead--
Acts 4:3 and they laid hands upon them, and did put them in custody unto the morrow, for it was evening already;
Acts 4:4 and many of those hearing the word did believe, and the number of the men became, as it were, five thousand.
The verse centers on "grieved", "teaching", "people", "preaching", "jesus", "rising", "again", and "dead--". It is saying that the verse draws attention to "grieved" and "teaching", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 1's "And as they are speaking unto the..." into verse 3's "and they laid hands upon them and...", so "grieved" and "teaching" belong inside that flow. In Acts context, the local focus is Christ, faith, and discipleship.
A plain takeaway is to answer the verse's own emphasis on "grieved" and "teaching" with trust shaped by these words, not by a vague optimism outside the passage.
