Jesus' second coming is the Final Judgment of Matthew 25. If you confess just before He arrives that's fine. If you happen to die in a car crash, it is a parallel situation: when time is up, time is up. Let us be sure we're confessing regularly. Remember to repent of serious sin immediately: sincere sorrow with an Act of Contrition, and then get to Confession ASAP! Padrepiofan, try not to get caught up in legalism. Love Jesus and hate sin. Beware of which sins you are most susceptible to and avoid the obvious circumstances. Jesus, I trust in Thee!
