Judgement

5But they will have to give account to him who is ready to judge the living and the dead. 6For this is the reason the gospel was preached even to those who are now dead, so that they might be judged according to men in regard to the body, but live according to God in regard to the spirit.
--1 Peter 4:5-6

Judgement is not our favorite word. In fact religion and judgement is a word pair that turns people off as if you were cussing in their face. But judgement is a cold reality. "Judgement" has a finality about it. Capital "J" "Judgement" basically just means that there is a point in time when consequences will be measured out. In this sense everyone believes in Judgement because death is an ever-present reality. Though our world hates the idea of Judgement and acts as though only silly religious people would believe in something so archaic, in fact the opposite is true. Christians, in fact, can face the idea of Judgement boldly because we believe that in reality it doesn't apply to us. We are excused from it. We all tend to live with this fear that someday life is all going to come crashing down on us--that's nothing more than a practical concession to the reality of judgement. But living by the Spirit enables us to believe firmly that everything really is going to be ok.
