We got the New Testament from the
Apostles of Jesus.

Most of them were his disciples and had
walked with Jesus personally and witnessed
his teachings and miracles on earth.

Many copies were made and protected by
those in the churches. Later other writings
appeared which were forgeries. They contained
outlandish claims even of Jesus.

These writings were protected and kept for
later generations so that they were not only
lost but changed in any way.

Jesus said "Teaching them to observe all
things whatsoever I have commanded you; and
lo, I am with you always, even unto the end of
the world." Matt. 28:20 Refering to himself
and His Word....they are one nd the same.

After they were all gone, it was God himself that
had His hand on His Word to keep them safe and
preached throughout the decades.
