Absolutely God allowed His word to go through a process of purification and growth. Remember, the word perfect generally means complete. The original autographs were never put together into one whole volume. God allowed His word to be preserved and translated also, and especially when His word was translated into English, that is where we see the purification process really taking off through the several different English Bibles, Great, Coverdale, Bishop's, Geneva, and so forth. Those very English Bibles which I just mentioned were all blessed By God and God did use them. For they also were pure Bibles. When God allowed His word to go through this purification process in the English tongue, even the English language was being perfected also, at the same time. Absoutely perfection and completion came in 1611, in the blessed King James Holy Bible.
Even Jesus Himself went through a process of Growth. God the Father allowed Even His only begotten Son Jesus to go through a process of growth to where He was made perfect through the things which He had suffered (Hebrews 5:8-9)
