John 12:46

I have come into the world to be a light [to it], so that whoever believes in me would not have to remain in [spiritual] darkness.

1 Corinthians 13:12

For now [i.e., during the church's infant state] we see in a mirror [Note: God's word is elsewhere likened to a mirror. See James 1:22-25] indistinctly [i.e., because of having only partial knowledge and prophecy], but then [i.e., when the church matures and has the completed Scriptures], we will see face to face [i.e., clearly]. Now I have [only] partial knowledge, but then I will have full knowledge, just as [God has] full knowledge of me.

2 Peter 1:19

And we have the message of the prophets [confirmed to us] as more certain [than ever]. So, you will do well to pay careful attention to it, as [you would] to a lamp in a dark place, until the day dawns and the morning star rises in your hearts [Note: This probably refers to the beginning of the Gospel age, when people would become enlightened to its message].
