Chapter 35.—Unless Infants are Baptized, They Remain in Darkness. “I am come,” says Christ, “a light into the world, that whosoever believeth on me should not abide in darkness.” 321 Now what does this passage show us, but that every person is in darkness who does not believe on Him, and that it is by believing on Him that he escapes from this permanent state of darkness? What do we understand by the darkness but sin?
