In whom we have redemption through his blood, the forgiveness of sins, according to the riches of his grace. Ephesians 1:7.
(WGD 234.1)
Our condition through sin has become preternatural, and the power that restores us must be supernatural, else it has no value. There is but one power that can break the hold of evil from the hearts of men, and that is the power of God in Jesus Christ. Only through the blood of the Crucified One is there cleansing from sin.
(WGD 234.2)
His grace alone can enable us to resist and subdue the tendencies of our fallen nature. This power the spiritualistic theories concerning God make of no effect. If God is an essence pervading all nature, then He dwells in all men; and in order to attain holiness, man has only to develop the power that is within him.—Testimonies for the Church 8:291.
(WGD 234.3)
You may have the overcomer’s reward, and stand before the throne of Christ to sing His praises in the day when He assembles His saints; but your robes must be cleansed in the blood of the Lamb, and charity must cover you as a garment, and you be found spotless and without blemish. John says: After this I beheld and, lo, a great multitude, which no man could number, of all nations, and kindreds, and people, and tongues, stood before the throne, and before the Lamb, clothed with white robes, and palms in their hands; and cried with a loud voice, saying, Salvation to our God which sitteth upon the throne, and unto the Lamb.” “These are they which came out of great tribulation, and have washed their robes, and made them white in the blood of the Lamb.... They shall hunger no more, neither thirst any more; neither shall the sun light on them, nor any heat.”—Testimonies for the Church 4:125.
