But of him are ye in Christ Jesus, who of God is made unto us wisdom, and righteousness, and sanctification, and redemption: that, according as it is written, He that glorieth, let him glory in the Lord. 1 Corinthians 1:30, 31. YRP 66.1
Just here we might distinguish between genuine and false sanctification. Sanctification does not consist in merely professing and teaching the Word of God, but in living in conformity to His will. Those who claim to be sinless, and make their boast of sanctification, are self-confident, and do not realize their peril. They anchor their souls upon the supposition that having once experienced the sanctifying power of God, they are in no danger of falling. While claiming to be rich and increased in goods, and in need of nothing, they know not that they are miserable, and poor, and blind, and naked. YRP 66.2
But those who are truly sanctified have a sense of their own weakness. Feeling their need, they will go for light and grace and strength to Jesus, in whom all fullness dwells, and who alone can supply their wants. Conscious of their own imperfections, they seek to become more like Christ, and to live in accordance with the principles of His holy law. This continual sense of inefficiency will lead to such entire dependence upon God that His Spirit will be exemplified in them. The treasures of heaven will be opened to supply the wants of every hungering, thirsting soul. All of this character have the assurance of one day beholding the glory of that kingdom which as yet the imagination can only faintly grasp. YRP 66.3
Those who have felt the sanctifying and transforming power of God must not fall into the dangerous error of thinking that they are sinless, that they have reached the highest state of perfection, and are beyond the reach of temptation. The standard the Christian is to keep before him is the purity and loveliness of Christ's character. Day by day he may be putting on new beauties, and reflecting to the world more and still more of the divine image.—The Bible Echo, February 21, 1898. YRP 66.4
