Men in responsible positions should improve continually. They must not anchor upon an old experience and feel that it is not necessary to become scientific workers. Man, although the most helpless of God's creatures when he comes into the world, and the most perverse in his nature, is nevertheless capable of constant advancement. He may be enlightened by science, ennobled by virtue, and may progress in mental and moral dignity, until he reaches a perfection of intelligence and a purity of character but little lower than the perfection and purity of angels. With the light of truth shining upon the minds of men, and the love of God shed abroad in their hearts, we cannot conceive what they may become nor what great work they may do. 1TT 479.3
I know that the human heart is blind to its own true condition, but I cannot leave you without making an effort to help you. We love you, and we want to see you pressing on to victory. Jesus loves you. He died for you, and He wants you to be saved. We have no disposition to hold you in -----; but we do want you to make thorough work with your own soul, to right every wrong there, and make every effort to master self, lest you miss heaven. This you cannot afford to do. For Christ's sake, resist the devil, and he will flee from you. 1TT 480.1

The work of pruning and purifying to fit us for heaven is a great work and will cost us much suffering and trial, because our wills are not subjected to the will of Christ. We must go through the furnace till the fires have consumed the dross and we are purified and reflect the divine image. Those who follow their inclinations and are governed by appearances are not good judges of what God is doing. They are filled with discontent. They see failure where there is indeed triumph, a great loss where there is gain; and, like Jacob, they are ready to exclaim, “All these things are against me” (Genesis 42:36), when the very things whereof they complain are all working together for their good. 1TT 480.2
No cross, no crown. How can one be strong in the Lord without trials? To have strength we must have exercise. To have strong faith, we must be placed in circumstances where our faith will be exercised. The apostle Paul, just before his martyrdom, exhorted Timothy: “Be thou partaker of the afflictions of the gospel according to the power of God.” 2 Timothy 1:8. It is through much tribulation that we are to enter the kingdom of God. Our Saviour was tried in every possible way, and yet He triumphed in God continually. It is our privilege to be strong in the strength of God under all circumstances and to glory in the cross of Christ.—1872, Testimonies for the Church 3:67. 1TT 480.3
