Those who would share the benefits of the Saviour's mediation should permit nothing to interfere with their duty to perfect holiness in the fear of God. The precious hours, instead of being given to pleasure, to display, or to gain seeking, should be devoted to an earnest, prayerful study of the word of truth. The subject of the sanctuary and the investigative judgment should be clearly understood by the people of God. All need a knowledge for themselves of the position and work of their great High Priest. Otherwise it will be impossible for them to exercise the faith which is essential at this time or to occupy the position which God designs them to fill. Every individual has a soul to save or to lose. Each has a case pending at the bar of God. Each must meet the great judge face to face. How important, then, that every mind contemplate often the solemn scene when the judgment shall sit and the books shall be opened, when, with Daniel, every individual must stand in his lot, at the end of the days.

All who have received the light upon these subjects are to bear testimony of the great truths which God has committed to them. The sanctuary in heaven is the very center of Christ's work in behalf of men. It concerns every soul living upon the earth. It opens to view the plan of redemption, bringing us down to the very close of time and revealing the triumphant issue of the contest between righteousness and sin. It is of the utmost importance that all should thoroughly investigate these subjects and be able to give an answer to everyone that asketh them a reason of the hope that is in them.

The intercession of Christ in man's behalf in the sanctuary above is as essential to the plan of salvation as was His death upon the cross. By His death He began that work which after His resurrection He ascended to complete in heaven. We must by faith enter within the veil, “whither the forerunner is for us entered.” Hebrews 6:20. There the light from the cross of Calvary is reflected. There we may gain a clearer insight into the mysteries of redemption. The salvation of man is accomplished at an infinite expense to heaven; the sacrifice made is equal to the broadest demands of the broken law of God. Jesus has opened the way to the Father's throne, and through His mediation the sincere desire of all who come to Him in faith may be presented before God. 

“He that covereth his sins shall not prosper but whoso confesseth and forsaketh them shall have mercy.” Proverbs 28:13. If those who hide and excuse their faults could see how Satan exults over them, how he taunts Christ and holy angels with their course, they would make haste to confess their sins and to put them away. Through defects in the character, Satan works to gain control of the whole mind, and he knows that if these defects are cherished, he will succeed. Therefore, he is constantly seeking to deceive the followers of Christ with his fatal sophistry that it is impossible for them to overcome. But Jesus pleads in their behalf His wounded hands, His bruised body; and He declares to all who would follow Him: “My grace is sufficient for thee.” 2 Corinthians 12:9. “Take My yoke upon you, and learn of Me; for I am meek and lowly in heart: and ye shall find rest unto your souls. For My yoke is easy, and My burden is light.” Matthew 11:29, 30. Let none, then, regard their defects as incurable. God will give faith and grace to overcome them.
