Till ye be left as a beacon upon the top of a mountain, and as an ensign on an hill (Isa 30:17).
There’s a paradoxical relationship between light and darkness. Light drowns out light while darkness discloses light.
You can’t see a beacon in daylight. Sunshine drowns out the beacon. The beacon can only been seen at night, even if it was shining day and night.
Many unbelievers lead sunshiny lives. Natural light blinds them to the heavenly light.
The lives of many believers are darkened by hardship and heartache. Yet as their life grows outwardly darker, that is when heaven’s beacon burns more brightly in the distance.
It’s only because their lives are darkened by affliction that they can more clearly see the guiding light, as it leads them and beckons them onward and upward to Mt. Zion.
