Revelation 3:7-13 NIV

““To the angel of the church
in Philadelphia write:
These are the words of him
who is holy and true,
who holds the key of David.
What he opens no one can shut,
and what he shuts no one can open.
I know your deeds.
See, I have placed before you
an open door that no one can shut.
I know that you have little strength,
yet you have kept my word
and have not denied my name.
I will make those
who are of the synagogue of Satan,
who claim to be Jews though they are not,
but are liars—
I will make them come
and fall down at your feet
and acknowledge that I have loved you.
Since you have kept my command
to endure patiently,
I will also keep you from the hour of trial
that is going to come on the whole world
to test the inhabitants of the earth.
I am coming soon.
Hold on to what you have,
so that no one will take your crown.
The one who is victorious
I will make a pillar in the temple of my God. Never again will they leave it.
I will write on them the name of my God
and the name of the city of my God,
the new Jerusalem,
which is coming down out of heaven
from my God;
and I will also write on them my new name. Whoever has ears, let them hear what the Spirit says to the churches.”

“They preached the gospel in that city
and won a large number of disciples.
Then they returned to Lystra,
Iconium and Antioch,
strengthening the disciples
and encouraging them to remain true
to the faith.
“We must go through many hardships
to enter the kingdom of God,” they said.
Paul and Barnabas appointed elders for them
in each church and,
with prayer and fasting,
committed them to the Lord,
in whom they had put their trust.
After going through Pisidia,
they came into Pamphylia,
and when they had preached
the word in Perga,
they went down to Attalia.
From Attalia they sailed back to Antioch,
where they had been committed
to the grace of God for the work
they had now completed.
On arriving there,
they gathered the church together
and reported all that God
had done through them
and how he had opened a door of faith
to the Gentiles.
And they stayed there a long time
with the disciples.”
