The verse centers on "suddenly", "great", "earthquake", "foundations", "prison", "shaken", "immediately", and "doors". It is saying that the verse draws attention to "suddenly" and "great", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 25's "But about midnight Paul and Silas were..." into verse 27's "The jailer being roused out of sleep...", so "suddenly" and "great" 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 "suddenly" and "great" with trust shaped by these words, not by a vague optimism outside the passage.
