As you read Jesus’s words to the church in Philadelphia did you note that there were no “faults” listed for this Body of Believers? But the Lord does encourage them to remain faithful so that they can receive their reward.
Revelation 3:11 I am coming soon. Hold on to what you have, so that no one will take your crown. 12 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.
