An Introduction to the Book of Revelation

says that keeping the words is confirmed by obeying the commandment.
Consequently we enjoy the tree of life and enter the new heavenly
Jerusalem.
REVELATION AND THE OLD TESTAMENT
The Holy Bible starts with the book of Genesis to declare
God's care and appreciation of man. He offers him everything and
leaves him in need of nothing. However, man is soon expelled from
Paradise and he is grieved by a feeling of loneliness, even when he is
among many people. This is due to his isolation from God, the
Source of his life, peace and happiness. The Holy Scripture existed
to point to the Savior Messiah who, alone, can carry man to the divine
bosom once more and restore his dignity anew etc. We realized
in our comparison between Genesis and Revelation how the book of
Revelation had fulfilled the integrity of scriptural promises forever.
No one could imagine that it was possible to conclude the Holy Bible
without this book, which carries us to complete victory and participation
in the glories.
On of the scholars tried to make a comparison between what
is mentioned in the Old Testament and what is fulfilled in Revelation;
it filled about 17 pages. Some people thought that Revelation is a
Christian perusal of the Old Testament, aiming at enlightening the
history of church in her living present, which is based on an effective
past, and at leading the people to the Lord's great day 23 .
Some of those who studied 24 the book offered us an example
of this, as mentioned in Rev. 22:1-3, how it fulfills what was
mentioned in Gen. 2:9; Ezek. 47:1; Zech. 14:8.
"And he showed me a pure river of water of life, clear as
crystal, proceeding from the throne of God and of the Lamb.
In the middle of its street (market).
And on either side of the river, was the tree of life, which
bore twelve fruits, each tree yielding its fruit every month. And the
leaves of the tree were for the healing of the nations.
