That doesn't make sense to me, frankly. It really is more a strange, Medieval, sense of justice that underlies the notion. God through Christ has provided a way for us to be saved, but there still is a price to be paid for transgressing in the first place.
Do you believe that God does not punish unjust actions that are committed by Christians?
If you take the verses below, for example, what exactly is it that you think you are going to receive, for the evil that you have done in your body?
2 Corinthians 5:1–21
5 For we know that if
kthe tent that is
lour earthly home is destroyed, we have a building from God,
ma house not made with hands, eternal in the heavens. 2 For in this tent
nwe groan, longing to
oput on our heavenly dwelling, 3 if indeed by putting it on
1 we may not be found naked. 4 For while we are still in this tent, we groan, being burdened—not that we would be unclothed, but that we would be further clothed, so that what is mortal
pmay be swallowed up by life. 5 He who has prepared us for this very thing is God,
qwho has given us the Spirit as a guarantee.
6 So we are always of good courage. We know that
rwhile we are at home in the body we are away from the Lord, 7 for
swe walk by faith, not
tby sight. 8 Yes, we are of good courage, and we
uwould rather be away from the body and at home with the Lord. 9 So whether we are at home or away, we make it our aim to
vplease him. 10
For we must all appear before the judgment seat of Christ, xso that each one may receive what is due for what he has done in the body, whether good or evil.
