Where Genesis is God's beginning of the
world and man....Revelation is the end.
All the other books are associated with
one or the other.

Revelation means to unveil (making clear)
or to uncover (seen plain by all)

Genesis 3:8 "And they heard the voice of
the Lord God". . . . .when man began
walking with God.

Revelation 3:21 "To him that overcometh
will I grant to sit with me in my throne." . . .
when man is living with God forever.
