John 1:1
The Word [already] existed in the beginning [of time]. [Note: This is a reference to the preexistence of Jesus. See verse 14]. And the Word was with God and the Word was [what] God [was].
John 1:5
And [His] light continued to shine, [even] in the darkness [of the world], and that darkness did not overcome Him [or, did not fully understand Him].

[Now] the true Light, who enlightens all mankind, was [indeed] coming into the world [i.e., to earth].
John 8:12
So, Jesus spoke to them again [i.e., to the Jewish authorities. See 7:45], saying, "I am the light of the world. The person who becomes my follower will never live in [spiritual] darkness, but have the light of [i.e., for his] life [i.e., followers of Jesus will not live in error and sin but in truth and righteousness]."
Revelation 1:20
The secret of the seven stars that you saw in my right hand and the seven golden lampstands [is this]: The seven stars are the angels [i.e., messengers] of the seven churches. And the seven lampstands are the seven churches."
Revelation 2:5
So, remember where you have fallen from and repent [i.e., change your hearts and lives] and do the things you did at first [i.e., when you were first converted], or else I will come and remove your lampstand from its place [i.e., I will not permit the congregation to survive], unless you repent.
