The question that perplexes many Christians is how can I be sure I am saved? The topic of the investigative judgement, a heavenly tribunal that investigates the cases of professed believers sheds some light on this question. There can be no greater event in history, yet very few are interested in the results of this tribunal which affects the destiny of everyone who has ever lived on earth. A battle rages over the souls of men, a battle which also includes the vindication of God's character and law. The investigative judgement is one of the most exciting doctrines in the Bible, because it reveals Christ as the all powerful Mediator.
