The verse centers on "Spirit", "brought", "seen", "immediately", "troubled", "thrown", "down", and "upon". It is saying that the verse draws attention to "Spirit" and "brought", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 18's "Who answering them said O incredulous generation..." into verse 20's "And he asked his father How long...", so "Spirit" and "brought" 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 "brought" with trust shaped by these words, not by a vague optimism outside the passage.
