The Father is the true light, that Jesus brought to the world, that the Father brought into the world through His son. The Father reconciling us to Himself, through Jesus, working through Jesus. The Father's full expression of Himself, dwelt in Christ.
In 1 John 1:7 it says, and the blood of
His son, showing he has been talking about the Father. The God, and Father of the son. Here I think this is the only way I can show you...
1 That which was from the beginning, which we have heard, which we have seen with our eyes, which we have looked upon, and our hands have handled, of the Word of life
(we will see he is not referring to the person Jesus because it was manifested in Christ, meaning Jesus displayed it, but it was God the Father they were seeing, while it was Jesus they looked upon, heard, and handled, John is referring to that life, that word of truth, that was displayed); 2 (
For the life was manifested (in Jesus), and we have seen it, and bear witness, and shew unto you that eternal life
(now obviously, as you can see, he is not showing us Jesus, because Jesus is now in heaven, he is showing us the truth, that dwelt in Christ, as he will tell us, this is what they heard from Jesus (verse 5), seen, and handled, and that truth is that God is light, and in him is no darkness at all, which he will tell us starting from verse 5), which was with the Father
(true life), and was manifested unto us
(in Jesus)); 3 That which we have seen and heard declare we unto you
(they not only heard the truth, but seen the truth action, they seen the expression of God the Father in flesh, in Jesus), that ye also may have fellowship with
us: and truly our fellowship is with the
Father, and with
his Son Jesus Christ
(yes our fellowship is with the disciples, and the Father, and son, if we walk in the truth, notice no mention of the Holy Spirit, but also notice this also defines for us the Father and son, because verse 7 is going to reveal the 'God” John has been talking about from verse 5 to verse 7). 4 And these things write we unto you, that your joy may be full. 5 This then is the message which we have heard of him
(Jesus, who spoke to them about the Father, that was in heaven, in the Gospels), and declare unto you, that God
(now I can show God is the light from N/T, and O/T, even from this passage it can be seen) is light, and in him
(Father, is truth, and in Him there is no lie, for He is love) is no darkness at all. 6 If we say that we have fellowship with him
(Father, if we follow the flow of whats written, we will see, John is talking about no one else, but the Father because it's only the Father that has a son Jesus, not unless you now want to say, the Son is the Son, of the Son, because the Holy Spirit is not even mentioned), and walk in darkness, we lie, and do not the truth
(darkness here is the lie, light is truth, if we don't do the truth, we believe a lie): 7 But if we walk in the light, as he
(Father, has to be, because he has a son Jesus Christ...) is in the light, we have fellowship one with another, and the blood of Jesus Christ
his (Father's) Son cleanseth us from all sin.
Now you can put understanding to John 1, remembering, and keeping in mind, Light is truth, and it's in the Father, and came out of the Father. As verse 9 of John 1 says, the true light, which we know from 1 John 1 is speaking of the Father. And the Word is the Word of life, that Jesus spoke, and lived. Jesus is this Word of God, that came down, to do all that God sent it to do, but does not mean before this, God's Word was another person.
Isaiah 55:10 (KJV) For as the rain cometh down
(Word came down and became Christ), and the snow from heaven, and returneth not thither, but watereth the earth, and maketh it bring forth and bud
(Christ is the living water that brings life), that it may give
seed to the sower(sound familiar? seed is the Word of God, and the Word became flesh and brings life, and we confess the word), and
bread to the eater (Christ is the true bread of life that came down, we are to eat at his table, taking in his doctrine): 11 So shall my
word (that Word that came down and became flesh, dwelt in Christ, Christ is the Word of God, the Word that brings life and truth) be that goeth
forth out of my mouth (remember Christ said he came forth and was sent by the Father John 17:8, and speaks the words of God, Jesus is the [Logos: expressing the thoughts of the Father through the Spirit, is a broad term meaning "reasoning expressed by words”]): it shall not return unto me void
(the Word came down and dwelt among us, then returned to God accomplishing all of God's will), but it shall accomplish that which I please, and it shall prosper in the thing whereto
I sent it(remember Christ said he came forth and was sent by the Father John 17:8, Jesus did not come of his own authority, own initiative, or to do his own will John 3:34; 6:38; 7:28; 8:42).
Psalm 40:6(KJV) Sacrifice and offering thou didst not desire;
mine ears hast thou opened (he grew in Spirit, God put His law in his heart, he was given the spirit of God the implanted Word without measure Isaiah 55:11): burnt offering and sin offering hast thou not required. 7 Then
said I,
Lo,
I come: in the volume of the book it is written of me (Jesus, and here is something to keep in mind when reading scripture, we are his body), 8 I delight to do
thy (Father) will, O
my God (the Father): yea,
thy(Father) law is within
my (Jesus) heart (again the Word and God's love was in Christ).
In John 1:1 Up to verse 5 it speaks of the Father's light, which will become flesh in verse 14, then from verse 6-8 it speaks of the witness of John, of Father's light in Jesus. Then starting from verse 10 it speaks of the Father's light in Christ, then verse 14 it speaks of that true light becoming Jesus. The Word is God's expressed thoughts, reason, His Breath, His Spirit. All things were made by that breath. In that breath, was life and truth. And that life is the light, which we find out in verse 9, is the true light, that brings life, and truth to all that come into the world.
