"Remembering without ceasing your work of faith, and labor of love, and patience of hope in our Lord Jesus Christ, in the sight of God and our Father."  1 Thessalonians 1:3

It is air and exercise that keep the body healthy. So it is spiritually. The graces of the Spirit need to be often exercised and well aired to keep them healthy--aired with the pure breath of heaven, and exercised with the operations of the Holy Spirit drawing them forth into activity and energy. And just as in nature a man gains health and strength by using his limbs and working his muscles, so in spiritual things these graces of the Spirit gain strength by use and exercise. Faith by working hard, hope by enduring much, and love by laboring long in the face of difficulties, become each more strengthened, more confirmed, more active, healthy, and energetic.

It is a false faith to sleep all day in the sluggard's arm-chair; it is the hypocrite's hope who endures nothing for Christ's sake; it is love in 'lip and tongue and name' that undergoes no labor to please the beloved Object. Look at these things in the light of your own experience. See whether you can find not only faith in your heart, but its work; not only hope, but its patience; not only love, but its labor. The Apostle remembered without ceasing their work of faith, and labor of love, and patience of hope. His eye was fixed not so much upon their Christian graces as their exercises of them, and as he saw their faith working diligently, their hope suffering patiently, and their love laboring unweariedly for the glory of God and the good of his people, he was satisfied they were the graces of the Spirit wrought in their heart by a divine power.
