While I agree with Chuck and believe that he is correct, that in the flesh, we cannot be perfect. I also believe once we've received the holy. We are to walk in that spirit and in that spirit we can be, and should be, perfect without sin. What did Jesus say to the adultererous "go and sin no more" I believe the "Church" will be the Christians that have received the Holy Spirit (Born-again Christians) and live in the Spirit, the others, the Christians that thought they were following Jesus, but had never fully repented of sin, will find salvation, but only as if by fire, in the tribulation.
