Christ doth not pray that his Father would take up his saints out of this sinful and troublesome world into heaven, because he knew that they were to be of use to him for a time in the world; but he prays that the Lord would keep them from the evil one, (so some would have it translated), or from the evil thing; by which we must not understand what is penally and afflictively evil, but only what is sinfully evil: and by his example he hath directed us how we ought to pray; not for death, nor absolutely for a deliverance from the evils and miseries of this life; but that we may be delivered from those temptations to sin, to which a multitude of sharp trials and afflictions will expose even the best of men.
