Isaias 26:9

“And the light shineth in darkness and the darkness hath not overtaken it.” We are still enquiring about the light of men, since it is what was spoken of in the preceding verse, and also, I consider, about darkness, which is named as its adversary, the darkness also being, if the definition of it is correct, that of men. The light of men is a generic notion covering two special things; and with the darkness of men it is the same. He who has gained the light of men and shares its beams will do the work of light and know in the higher sense, being illuminated by the light of the higher knowledge.

We are diligent in assembling ourselves together, for we were scattered in time past and were lost, and are found. We were far off, and are brought nigh, we were strangers, and have become His, Who suffered for us, and was nailed on the cross, Who bore our sins, as the prophet saith, and was afflicted for us, that He might put away from all of us grief, and sorrow, and sighing. …
