Many are longing to grow in grace; they pray over the matter, and are surprised that their prayers are not answered. The Master has given them a work to do whereby they shall grow. Of what value is it to pray when there is need of work? The question is, Are they seeking to save souls for whom Christ died? Spiritual growth depends upon giving to others the light that God has given to you. You are to put forth your best thoughts in active labor to do good, and only good, in your family, in your church, and in your neighborhood.
In place of growing anxious with the thought that you are not growing in grace, just do every duty that presents itself, carry the burden of souls on your heart, and by every conceivable means seek to save the lost. Be kind, be courteous, be pitiful; speak in humility of the blessed hope; talk of the love of Jesus; tell of His goodness, His mercy, and His righteousness; and cease to worry as to whether or not you are growing. Plants do not grow through any conscious effort. . . . The plant is not in continual worriment about its growth; it just grows under the supervision of God.
The only way to grow in grace is to be interestedly doing the very work Christ has enjoined upon us to do--interestedly engaged to the very extent of our ability to be helping and blessing those who need the help we can give them. . . . Christians who are constantly growing in earnestness, in zeal, in fervor, in love--such Christians never backslide. . . . Their wisdom is increasing, {and} their ability {in} how to work. They seem to comprehend the largest plans. They are ready to engage in the most stirring enterprises, and they have no room for slothfulness; they cannot find a place for stagnation.
The treasures of grace are absolutely unlimited. ML 103
Through the co-operation of the divine Spirit the labors of the humble men whom Christ had chosen stirred the world. To every nation under heaven was the gospel carried in a single generation. Ed 95
And God is able to make every grace overflow to you, so that in every way, always having everything you need, you may excel in every good work. 2 Corinthians 9:8 (Holman Christian Standard Bible)
