The Church of Philadelphia

The church in Philadelphia is one of the two churches (the other being Smyrna) with which the Lord finds no particular fault. There is no word of condemnation, only commendation.
This church is not told to repent (cf. 2:5, 16, 21; 3:3, 19). Our Lord addresses the church as “He that is holy, He that is true” (3:7). These are divine attributes.
First John 5:20 says, “And we know that the Son of God is come, and hath given us an understanding, that we may know Him that is true, and we are in Him that is true, even in His Son Jesus Christ. This is the true God, and eternal life.” First Peter 1:15, 16 says, “But as He which hath called you is holy, so be ye holy in all manner of conversation; Because it is written, Be ye holy; for I am holy.”
