The verse centers on "keeper", "prison", "waked", "sleepe", "sawe", "doores", and "open". It is saying that the verse draws attention to "keeper" and "prison", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 26's "And suddenly there was a great earthquake..." into verse 28's "But Paul cryed with a loude voyce...", so "keeper" and "prison" 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 "keeper" and "prison" with trust shaped by these words, not by a vague optimism outside the passage.
