"And unto the angel of the church in Sardis write; These things saith he that hath the seven Spirits of God, and the seven stars; I know thy works, that thou hast a name that thou livest, and art dead." (Revelation 3:1)
The church at Sardis received the saddest of the Lord's seven letters in Revelation. Sardis seemed to want to remain known as a "live" church, but the Lord saw their real testimony and reputation and concluded that they were "dead." Many such places around the world today are enshrined with stained glass, statuary, crosses, and inscriptions that have the "name" of Christianity emblazoned throughout their property, yet they are dead spiritually. Such churches might be compared to the monuments and gravestones erected in cemeteries to honor the memories of faithful men and women of past generations who were alive for a time with a solid reputation for godliness, yet whose families have drifted away from the Lord.
Yet "even in Sardis" there was a small number who had remained faithful in spite of the drift of the church itself, as there are also in families now adrift but with a Christian heritage. The advice to Sardis (and certainly to families as well) is this: "Remember therefore how thou hast received and heard, and hold fast, and repent" (Revelation 3:3).
The Philippian church received the same counsel: "Those things, which ye have both learned, and received, and heard, and seen in me, do: and the God of peace shall be with you" (Philippians 4:9). The verb is "do." Heritage is wonderful, but each church--and each of us--will be held accountable for what is actually done. HMM III
