I believe it is possible for a heaven bound Christian to end up condemned. There are many passages describing this but I believe the parable in
Luke 12:42-46 is one of the clearest.
In this parable, the word "manager" is singular, showing that there is only one faithful and wise manager being spoken of. Looking at the verses, we have:
a) V.42 tells us of a faithful and wise manager (obviously a saved man) who is put in charge while the master (Jesus) is away.
b) Vs. 43-44 say that the servant will be rewarded and put in charge of all the master's possessions if the master returns and finds that the servant has remained faithful.
c) Vs. 45-46 then tells us that the same servant will be condemned and assigned a place with the unbelievers (in hell) if the master returns and finds that he is sinning and mistreating the other servants etc.
To say that the servant will be assigned a place with unbelievers makes it obvious that he was a believer initially.
To me, this is one of several parables and passages which clearly show that a Christian can be rewarded or condemned, depending on his actions.
Loss of salvation is a vitally important issue.
What do you think of this parable?
