After death, there is only the prospect of judgment—not a further opportunity for obedience (Hebrews 9:27). In the parable of the virgins, Jesus taught that in whatever condition one goes to “sleep,” i.e., dies, in exactly that same state he will meet the bridegroom (Matthew 25:1-13). Moreover, there is a permanent, impassible chasm between the place of punishment and that of reward, and no man can cross it (Luke 16:26). There is no post-mortem plan of salvation. Now is the day of redemption (2 Corinthians 6:2).
In other words purgatory does not exist.
