I saw that those who have no property, but have strength of body, are accountable to God for their strength. They should be diligent in business and fervent in spirit; they should not leave those that have possessions to do all the sacrificing. I saw that they can sacrifice, and that it is their duty to do so, as well as those who have property. But often those that have no possessions do not realize that they can deny themselves in many ways, can lay out less upon their bodies, and to gratify their tastes and appetites, and find much to spare for the cause, and thus lay up a treasure in heaven.—Testimonies for the Church 1:115. CS 121.2
Those who have physical strength are to employ that strength in the service of God. They are to labor with their hands, and earn means to use in the cause of God. Those who can obtain work are to work faithfully, and to improve the opportunities they see to help those who cannot obtain labor.—The Review and Herald, August 21, 1894. CS 122.1
