Some people receive all their reward in this world and no more afterwards. Some people suffer a lot (their purgatory?) in this life and reap their reward in their next. Some of us live a long life and others die early, all for the glory of God. I have lived beyond the normal life expectancy, believing that the Lord still has work for me to do. Nevertheless, whether we live long or short, get rewarded now or later, the whole point is that we get back to God.
