For mortals, therefore, the gospel is inexhaustible, because “the Spirit searcheth all things, yea, the deep things of God” (1 Corinthians 2:10). Jacob’s words are strikingly similar to Paul’s: “For the Spirit speaketh the truth . . . of things as they really are, and of things as they really will be” (Jacob 4:13). Unsurprisingly, the scriptural definition of truth matches. It is the “knowledge of things as they are, and as they were, and as they are to come” (D&C 93:24). What vastness!
