The great plan of redemption, as revealed in the closing work of these last days, should receive close examination. The scenes connected with the sanctuary above should make such an impression upon the minds and hearts of all that they may be able to impress others. All need to become more intelligent in regard to the work of the atonement, which is going on in the sanctuary above. When this grand truth is seen and understood, those who hold it will work in harmony with Christ to prepare a people to stand in the great day of God, and their efforts will be successful. By study, contemplation, and prayer God’s people will be elevated above common, earthly thoughts and feelings, and will be brought into harmony with Christ and His great work of cleansing the sanctuary above from the sins of the people. Their faith will go with Him into the sanctuary, and the worshipers on earth will be carefully reviewing their lives and comparing their characters with the great standard of righteousness. They will see their own defects; they will also see that they must have the aid of the Spirit of God if they would become qualified for the great and solemn work for this time which is laid upon God’s ambassadors.
