a. One mark of growth in grace is increased humility. The man whose soul is growing feels his own sinfulness and unworthiness more every year. He is ready to say with Job, "I am vile," and with Abraham, "I am dust and ashes," and with Jacob, "I am not worthy of the least of all Your mercies," and with David, "I am a worm," and with Isaiah, "I am a man of unclean lips," and with Peter, "I am a sinful man, O Lord" (Job 40:4; Gen. 18:27; 32:10; Ps. 22:6; Isa. 6:5; Luke 5:8). The nearer he draws to God and the more he sees of God’s holiness and perfections, the more thoroughly is he sensible of his own countless imperfections. The further he journeys in the way to heaven, the more he understands what Paul meant when he says, "I am not already perfect," "I am not meet to be called an apostle," "I am less than the least of all saints," "I am chief of sinners" (Phil. 3:12; 1 Cor. 15:9; Eph. 3:8; 1 Tim. 1:15). The riper he is for glory, the more, like the ripe corn, he hangs down his head. The brighter and clearer is his light, the more he sees of the shortcomings and infirmities of his own heart. When first converted, he would tell you he saw but little of them compared to what he sees now. Would anyone know whether he is growing in grace? Be sure that you look within for increased humility.
b. Another mark of growth in grace is increased faith and love towards our Lord Jesus Christ. The man whose soul is growing finds more in Christ to rest upon every year and rejoices more that he has such a Savior. No doubt he saw much in Him when first he believed. His faith laid hold on the atonement of Christ and gave him hope. But as he grows in grace, he sees a thousand things in Christ of which at first he never dreamed. His love and power, His heart and His intentions, His offices as Substitute, Intercessor, Priest, Advocate, Physician, Shepherd and Friend, unfold themselves to a growing soul in an unspeakable manner. In short, he discovers a suitableness in Christ to the wants of his soul, of which the half was once not known to him. Would anyone know if he is growing in grace? Then let him look within for increased knowledge of Christ.
c. Another mark of growth in grace is increased holiness of life and conversation. The man whose soul is growing gets more dominion over sin, the world and the devil every year. He becomes more careful about his temper, his words and his actions. He is more watchful over his conduct in every relation of life. He strives more to be conformed to the image of Christ in all things and to follow Him as his example, as well as to trust in Him as his Savior. He is not content with old attainments and former grace. He forgets the things that are behind and reaches forth unto those things which are before, making "Higher!" "Upward!" "Forward!" "Onward!" his continual motto (Phil. 3:13). On earth he thirsts and longs to have a will more entirely in unison with God’s will. In heaven the chief thing that he looks for, next to the presence of Christ, is complete separation from all sin. Would anyone know if he is growing in grace? Then let him look within for increased holiness.
d. Another mark of growth in grace is increased spirituality of taste and mind. The man whose soul is growing takes more interest in spiritual things every year. He does not neglect his duty in the world. He discharges faithfully, diligently and conscientiously every relation of life, whether at home or abroad. But the things he loves best are spiritual things. The ways and fashions and amusements and recreations of the world have a continually decreasing place in his heart. He does not condemn them as downright sinful, nor say that those who have anything to do with them are going to hell. He only feels that they have a constantly diminishing hold on his own affections and gradually seem smaller and more trifling in his eyes. Spiritual companions, spiritual occupations, spiritual conversation appear of ever–increasing value to him. Would anyone know if he is growing in grace? Then let him look within for increasing spirituality of taste.
f. One more mark of growth in grace is increased zeal and diligence in trying to do good to souls. The man who is really growing will take greater interest in the salvation of sinners every year. Missions at home and abroad, efforts of every kind to spread the gospel, attempts of any sort to increase religious light and diminish religious darkness—all these things will every year have a greater place in his attention. He will not become "weary in well–doing" because he does not see every effort succeed. He will not care less for the progress of Christ’s cause on earth as he grows older, though he will learn to expect less. He will just work on, whatever the result may be—giving, praying, preaching, speaking, visiting, according to his position—and count his work its own reward. One of the surest marks of spiritual decline is a decreased interest about the souls of others and the growth of Christ’s kingdom. Would anyone know whether he is growing in grace? Then let him look within for increased concern about the salvation of souls.
