Andrew, I think if you carry your translating of “him” to “it” to it’s logical conclusion, you will see that it doesn’t make a whole lot of sence. Every time the same word that you changed from “him” to “it” occurs in this passage, I have changed it when it refers to Jesus. For ease in seeing where all those changes are, I will be putting them in all caps throughout the passage.
(This is the Net Bible version quoted below. https://net.bible.org/#!bible/John+1)
So here goes:
1:1 In the beginning1 was the Word, and the Word was with God,2 and the Word was fully God.3 1:2 The Word4 was with God in the beginning. 1:3 All things were created5 by IT, and apart fron IT not one thing was created6 that has been created.7 1:4 In IT was life,8 and the life was the light of mankind.9 1:5 And the light shines on10 in the darkness,11 but12 the darkness has not mastered it.13
1:6 A man came, sent from God, whose name was John.14 1:7 He came as a witness15 to testify16 about the light, so that everyone17 might believe through him. 1:8 He himself was not the light, but he came to testify18 about the light. 1:9 The true light, who gives light to everyone was coming into the world.20 1:10 He was in the world, and the world was created21 by IT, but22 the world did not recognize23 IT. 1:11 He came to what was his own,24 but25 his own people26 did not receive IT.27 1:12 But to all who have received IT – those who believe in IT’S name28 – he has given the right to become God’s children 1:13 – children not born29 by human parents30 or by human desire31 or a husband’s32 decision,33 but by God.
1:14 Now34 the Word became flesh35 and took up residence36 among us. We37 saw IT’S glory – the glory of the one and only,38 full of grace and truth, who came from the Father. 1:15 John39 testified40 about IT and shouted out,41 “This one was the one about whom I said, ‘He who comes after me is greater than I am,42 because he existed before me.’” 1:16 For we have all received from IT’S fullness one gracious gift after another.43 1:17 For the law was given through Moses, but44 grace and truth came about through Jesus Christ. 1:18 No one has ever seen God. The only one,45 himself God, who is in closest fellowship with46 the Father, has made God47 known.48
Whew, hope I got them all in there correctly. Now I suppose you can argue that the word doesn’t always have to be changed from “him” to “it”. But Jesus and the Word are so closely identified here, that I am not sure that it would be possible to consistently translate it any other way.
