Exodus 19:16 And the thirde day, when it was morning, there was thunders and lightnings, and a thicke cloude vpon the mount, and the sounde of the trumpet exceeding loude, so that all the people, that was in the campe, was afrayde.

The verse centers on "light", "thirde", "morning", "thunders", "lightnings", "thicke", "cloude", and "vpon". It is saying that the verse draws attention to "light" and "thirde", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 15's "And he said vnto the people Be..." into verse 17's "Then Moses brought the people out of...", so "light" and "thirde" belong inside that flow. In Exodus context, the local focus is covenant, worship, and faithfulness.
A plain takeaway is to answer the verse's own emphasis on "light" and "thirde" with trust shaped by these words, not by a vague optimism outside the passage.
