"The Key" from the Book of Revelation 3:7

2. Revelation 3:7
7 And to the angel of the church in
Philadelphia write; These things saith he that
is holy, he that is true, he that hath the key of
David, he that openeth, and no man shutteth;
and shutteth, and no man openeth;

3. John 10:7-10
7 Then said Jesus unto them again, Verily,
verily, I say unto you, I am the door of the
sheep.
8 All that ever came before me are thieves
and robbers: but the sheep did not hear them.

4. 9 I am the door: by me if any man enter in,
he shall be saved, and shall go in and out, and
find pasture.
10 The thief cometh not, but for to steal, and
to kill, and to destroy: I am come that they
might have life, and that they might have it
more abundantly.

5. Revelation 2:1-5
1 Unto the angel of the church of Ephesus
write; These things saith he that holdeth the
seven stars in his right hand, who walketh in
the midst of the seven golden candlesticks;

6. 2 I know thy works, and thy labour, and thy
patience, and how thou canst not bear them
which are evil: and thou hast tried them
which say they are apostles, and are not, and
hast found them liars:

7. 3 And hast borne, and hast patience, and for
my name's sake hast laboured, and hast not
fainted.
4 Nevertheless I have somewhat against thee,
because thou hast left thy first love.

8. 5 Remember therefore from whence thou art
fallen, and repent, and do the first works; or
else I will come unto thee quickly, and will
remove thy candlestick out of his place, except
thou repent.

9. Acts 3:19
Repent ye therefore, and be converted, that
your sins may be blotted out, when the times
of refreshing shall come from the presence of
the Lord;
