Here, I. Joshua directs them what to do, that they might persevere in religion, v. 11. Would we cleave to the Lord, and not forsake him, 1. We must always stand upon our guard, for many a precious soul is lost and ruined through carelessness: "Take heed therefore, take good heed to yourselves, to your souls (so the word is), that the inward man be kept clean from the pollutions of sin, and closely employed in the service of God." God has given us precious souls with this charge, "Take good heed to them, keep them with all diligence, above all keepings." 2. What we do in religion we must do from a principle of love, not by constraint or from a slavish fear of God, but of choice and with delight. "Lord the Lord your God, and you will not leave him."
