The greatest need of all of us is the need to be humble; our greatest lack is humility. It is our whole approach to God that is wrong, and the first great truth that we need to be taught is this truth that overrides everything else in the Word of God. It is the truth about God’s holiness, about God’s eternal judgements, and about His absolute righteousness. It is the truth that God is the Judge eternal. “Ah, but,” you say, “I am a Christian and I am surely not concerned about judgement.” The Bible does not tell you that. The whole Epistle to the Hebrews is a warning that we must meet God as Judge, and as Judge eternal. He is the one who shook the earth and who has now shaken the heavens. He is the judge of all men, and we must all appear before Him.
That is a part of the truth of sanctification; it is not something that need only be preached in an evangelistic meeting. It is of the very essence of sanctification, and is its first principle. Our God is a consuming fire! John puts it this way, in teaching sanctification in his epistle. The first thing he lays down concerning sanctification is this: “God is light and, in Him, is no darkness at all” (1 John 1.5); so, I suggest to you that we have no right to go on to consider any other aspects whatsoever of the truth of sanctification until we have realized that truth. And then John, having started with this emphasis concerning the truth about God, especially stresses, in following verses, that salvation is God’s plan.
