I just read a teaching on the site of a friend’s son. He has a post tribulation view. He states that “the church needs to go through the tribulation to be purified” and that pre-trib. believers will become disillusioned when we find that in truth we have to go through the tribulation.
People who teach that the Church has to be purified in the Great Tribulation do not understand what happened at the cross and are denying the Doctrine of Salvation by Grace. In effect they’re claiming that Jesus didn’t pay the full price for our sins, and that additional purification is necessary to qualify us for life in God’s presence. This contradicts the Bible’s clear teaching that our salvation is based exclusively on our belief. It’s also illogical because if they’re right then the generation alive at the time of the Great Tribulation is the only one that can be purified. Therefore all the previous generations of Church Age believers must be lost.
Paul wrote that our belief in the Lord’s completed work on the cross brings a righteousness that comes by faith (Romans 3:21-22). He said if anyone is in Christ he is a new creation (2 Cor.5:17) imbued with the righteousness of God (2 Cor. 5:21). The writer of Hebrews said that by His once for all time sacrifice, Jesus has made those who believe perfect forever (Hebr. 10:14). And Ephesians 5:25 -27 tells us Jesus died for us to make us holy, without stain or wrinkle or any other blemish, but holy and blameless. No additional purification is necessary or even possible.
