Those who teach by their doctrine must teach by their life, or else they pull down with one hand what they build up with the other.
Matthew HenryWhen he [the slothful person] is pressed to be diligent, either in his worldly affairs or in the business of religion, this is his excuse (and a sorry excuse it is as bad as none).
Matthew HenrySee what a hidden life the life of a good Christian is, and how much it is concealed from the eye and observation of the world. The most important part of the business lies between God and our own souls, in the frame of our spirits and the working of our hearts, in our actions that no eye sees except the all-seeing God. Justly are the saints called God's hidden ones, and His secret is said to be with them. They have meat to eat and work to do that the world does not know of, as well as joys, griefs, and cares that a stranger does not share.
Matthew Henry
