I find the apocryphal books simply eliminate themselves being out of harmony with the harmonious ' 66 '.
The ancient manuscripts are the oldest. So, No original Bibles, but the internal harmony in the ' 66' shows what is Not lost. The cross-reference corresponding verses and passages show even Jesus' recorded words used, thus Jesus could preface his statements with the words, " it is written...." meaning already written down in the old Hebrew Scriptures.
Since what was in the past came to pass, then the ' final signal ', so to speak, which is ahead of us is when ' they ' ( powers that be ) are saying," Peace and Security " according to 1 Thessalonians 5:2-3 is going to prove to be the precursor to the coming great tribulation of Revelation 7:14 before Jesus, as Prince of Peace, ushers in global Peace on Earth among people of goodwill.
Mankind has had thousands of years to establish peace and man's history shows man can't bring peace to Earth.
So, since man can't establish real peace, there will be divine involvement into mankind's affairs through Jesus.
That is why we are all invited to pray for Jesus to come as mentioned at Revelation 22:20 for Peace on Earth.
