Though it is the crowning work of our salvation and of the setting up of the kingdom of Christ upon earth, yet the "investigative judgment" is one of the least understood and most mystified and confused Bible subjects of the age. Were it not essential to our salvation, the enemy would not have expended every possible effort to envelop it in darkness. Imperative, then, is the unremitting need to search the Scriptures "as for hidden treasure," and to beseech God for the guidance of His Spirit in order rightly to understand this all-important subject. In vain, though, any search for truth unless the motive be to learn and to do the will of God. Hence, "if any man," says Jesus, "will do His will, he shall know of the doctrine, whether it be of God." John 7:17. Since the subject of the judgment is taught in types and in parables, and since the Lord explains that His teaching parabolically is so that only His disciples may know the mysteries of the kingdom of heaven (Matt. 13:11), obviously, therefore, none but His followers can understand the whole truth.
