When Jesus went down into hell [Hades]
God gave Him the
keys of that place.

He not only opened
the gates of Hades,
but took with Him
all the righteous
who were confined
there, including
David the king.

Jesus is now able to
fulfill the promises of
God's Covenant with David and, at His
Coming [return] He will occupy the Throne
of David.

The Philadelphia Church, will sit with Him
and rule with Him in His throne [Revelation
3:21].
