Yesterday I was asking myself that question, " who, what, when and why "
And the Holy spirit put me in my place.
I felt ashame for asking God why HE choose the Books and left out some.
2 Peter 1:20-21
20 knowing this first, that no prophecy of Scripture is of any private interpretation,[a] 21 for prophecy never came by the will of man, but holy men of God spoke as they were moved by the Holy Spirit

2 Timothy 3:16-17
16 All Scripture is given by inspiration of God, and is profitable for doctrine, for reproof, for correction, for instruction in righteousness, 17 that the man of God may be complete, thoroughly equipped for every good work.
I cant answer the question why some was left out because everything is in God's will and to try and break that code seem useless for me, I think how the Bible came together was perfect.
I'm sure when we get to heaven we can ask him, why He didn't add the other text.
