Be sure that you live not idly, but in some constant business of a lawful calling, so far as you have bodily strength. Idleness is a constant sin, and labour is a duty. Idleness is but the devil’s home for temptation, and for unprofitable, distracting musings. Labour profiteth others and ourselves; both soul and body need it. Six days must thou labour, and must not eat “The bread of idleness.” (Prov. 31:13-27.) God hath made it our duty, and will bless us in His appointed way. I have known grievous, despairing melancholy cured and turned into a life of godly cheerfulness, principally by setting upon constancy and diligence in the business of families and callings.
