I believe in the seven churches as ages...
Ephesus - Messianic - Beginning with the Apostle to the Circumcision, Peter
Smyrna - Martyr - Beginning with the Apostle to the Un-Circumcision, Paul
Pergamos - Orthodoxy formed in this time... Pergos is a tower... Needed in the dark ages
Thyatira - Catholicism formed in this time - The spirit of Jezebel is to control and to dominate.
Sardis - Protestantism formed in this time- A sardius is a gem - elegant yet hard and rigid
Philadelphia - Wesleyism formed in this time - To be sanctioned is to acquire it with love.
Laodicea - Charismatic movement formed in this time - Beginning with DL Moody, the first to make money off of ministry
In which the Lord makes it very clear to the Sardisean church...
4 Thou hast a few names even in Sardis which have not defiled their garments; and they shall walk with me in white: for they are worthy.
5 He that overcometh, the same shall be clothed in white raiment;
and I will not blot out his name out of the book of life, but I will confess his name before my Father, and before his angels.
6 He that hath an ear, let him hear what the Spirit saith unto the churches. - Revelation 3
This is a race in which we do not win until we cross the finish line...
And ye shall be hated of all men for my name's sake: but he that endureth to the end shall be saved - Matthew 10:22
And the Lord blots out names in the book of life according to his will...
31 And Moses returned unto the Lord, and said, Oh, this people have sinned a great sin, and have made them gods of gold.
32 Yet now, if thou wilt forgive their sin--; and if not, blot me, I pray thee, out of thy book which thou hast written.
33 And the Lord said unto Moses,
Whosoever hath sinned against me, him will I blot out of my book. - Exodus 32
