The Father tabernacled in the flesh named Jesus. God is Light and the Light of John's Prologue IS the Father Himself as expressed by Jesus in all the words and works Jesus was doing in the name of the Father. The flesh named Jesus expressed the Word of the Father, who/what the Father is: light, life, truth, love. He expressed the Father in the things he was doing, the works of the Father. It was the Father abiding in Jesus who did the works.
What does the following passage mean?
Now, little children [of the Father], abide in the [the Father] so that when He [the Father] appears, we may have confidence and not shrink away from [the Father] in shame at [the Father's] coming. If you know that He is righteous, you know that everyone also who practices righteousness is born of [the Father]. See how great a love the Father has bestowed on us, that we would be called children of God; and such we are. For this reason the world does not know us, because it did not know [the Father] (see Jn 17:25). Beloved, now we are children of God [the Father], and it has not appeared as yet what we will be. We know that when the [the Father] appears, we will be like [the Father], because we will see Him just as He is. And everyone who has this hope fixed on Him purifies himself, just as He is pure (see 1:5). 1 John 2:28-3:3. Read it carefully.
Then read Revelation 21:1-7; 22:1-5. See also 1 Timothy 6:14-16.
