If the soul is to be purified and ennobled, and made fit for the heavenly courts, there are two lessons to be learned—self-sacrifice and self-control. Some learn these important lessons more easily than do others, for they are exercised by the simple discipline the Lord gives them in gentleness and love. Others require the slow discipline of suffering, that the cleansing fire may purify their hearts of pride and self-reliance, of earthly passion and self-love, that the true gold of character may appear and that they may become victors through the grace of Christ. FW 86.3
The love of God will strengthen the soul, and through the virtue of the merits of the blood of Christ we may stand unscathed amid the fire of temptation and trial; but no other help can avail to save but Christ, our righteousness, who is made unto us wisdom and sanctification and redemption. FW 86.4
True sanctification is nothing more or less than to love God with all the heart, to walk in His commandments and ordinances blameless. Sanctification is not an emotion but a heaven-born principle that brings all the passions and desires under the control of the Spirit of God; and this work is done through our Lord and Saviour. FW 87.1
Spurious sanctification does not glorify God but leads those who claim it to exalt and glorify themselves. Whatever comes in our experience, whether of joy or sorrow, that does not reflect Christ and point to Him as its author, bringing glory to Him and sinking self out of sight, is not true Christian experience. FW 87.2
When the grace of Christ is implanted in the soul by the Holy Spirit, its possessor will become humble in spirit and will seek for the society of those whose conversation is upon heavenly things. Then the Spirit will take the things of Christ and show them unto us and will glorify, not the receiver, but the Giver. If, therefore, you have the sacred peace of Christ in your heart, your lips will be filled with praise and thanksgiving to God. Your prayers, the discharge of your duty, your benevolence, your self-denial, will not be the theme of your thought or conversation, but you will magnify Him who gave Himself for you when you were yet a sinner. You will say: “I give myself to Jesus. I have found Him of whom Moses in the law, and the prophets, did write.” As you praise Him you will have a precious blessing, and all the praise and glory for that which is done through your instrumentality will be given back to God.
