To all:
Some try to twist Revelation 3:5 to say that it is not referring to spiritual death.
However, people just fail to read and believe the context if they believe Revelation 3:5 is dealing with physical death only.
The whole context is dealing with how this church is spiritually dead.
They live physically, but they are dead spiritually. That is the starting of the context (with verse 1).
Revelation 3:1-6
1 “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.
2 Be watchful, and strengthen the things which remain, that are ready to die: for I have not found thy works perfect before God.
3 Remember therefore how thou hast received and heard, and hold fast, and repent. If therefore thou shalt not watch, I will come on thee as a thief, and thou shalt not know what hour I will come upon thee.
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.”
In this passage we see how Jesus will confess the one who overcomes to the Father.
We see a similar thing in Matthew 10.
Matthew 10:32-33
32 “Whosoever therefore shall confess me before men, him will I confess also before my Father which is in heaven.
33 But whosoever shall deny me before men, him will I also deny before my Father which is in heaven.”
Again, sounds like a salvation issue here because the contrast of confessing Him before men is denying Jesus before men and if that is the case, Jesus will deny that person before the Father. It does not sound like one is saved if Jesus denies a person before the Father. But I am sure Belief Alone Salvationists have found a way to change this passage beyond what it says plainly.
