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.
