I have been shown that those who have a knowledge of the truth, and yet allow all their powers to be absorbed in worldly interests, are unfaithful. They are not, by their good works, letting the light of truth shine to others. Nearly all their ability is devoted to becoming sharp, skillful men of the world. They forget that their talents were given them of God to be used in advancing His cause. If they were faithful to their duty, the result would be great gain of souls to the Master; but many are lost through their neglect. 2TT 96.1
God calls upon those who know His will to be doers of His word. Weakness, halfheartedness, and indecision provoke the assaults of Satan; and those who permit these traits to grow will be borne helplessly down by the surging waves of temptation. Everyone who professes the name of Christ is required to grow up to the full stature of Christ, the Christian's living head. 2TT 96.2
We all need a guide through the many strait places in life as much as the sailor needs a pilot over the sandy bar or up the rocky river, and where is this guide to be found? We point you, dear brethren, to the Bible. Inspired of God, written by holy men, it points out with great clearness and precision the duties of both old and young. It elevates the mind, softens the heart, and imparts gladness and holy joy to the spirit. The Bible presents a perfect standard of character; it is an infallible guide under all circumstances, even to the end of the journey of life. Take it as the man of your counsel, the rule of your daily life. 2TT 96.3
Every means of grace should be diligently improved that the love of God may abound in the soul more and more, “that ye may approve things that are excellent; that ye may be sincere and without offense till the day of Christ; being filled with the fruits of righteousness.” Philippians 1:10, 11. Your Christian life must take on vigorous and stalwart forms. You can attain to the high standard set before you in the Scriptures, and you must if you would be children of God. You cannot stand still; you must either advance or retrograde. You must have spiritual knowledge, that you “may be able to comprehend with all saints what is the breadth, and length, and depth, and height; and to know the love of Christ,” that you may “be filled with all the fullness of God.” Ephesians 3:18, 19. 2TT 96.4
Many who have an intelligent knowledge of the truth, and are able to defend it by arguments, are doing nothing for the upbuilding of Christ's kingdom. We meet them from time to time; but they bear no fresh testimonies of personal experience in the Christian life; they relate no new victories gained in the holy warfare. Instead of this you notice the same old routine, the same expressions in prayer and exhortation. Their prayers have no new note; they express no greater intelligence in the things of God, no more earnest, living faith. Such persons are not living plants in the garden of the Lord, sending forth fresh shoots and new foliage, and the grateful fragrance of a holy life. They are not growing Christians. They have limited views and plans, and there is no expansion of mind, no valuable additions to the treasures of Christian knowledge. Their powers have not been taxed in this direction. They have not learned to view men and things as God views them, and in many cases unsanctified sympathy has injured souls and greatly crippled the cause of God. The spiritual stagnation that prevails is terrible. Many lead a formal Christian life and claim that their sins have been forgiven, when they are as destitute of any real knowledge of Christ as is the sinner. 2TT 97.1
