{11} Be sober, be vigilant; because your adversary the devil, as a roaring lion, walketh about, seeking whom he may devour:

(11) The cruelty of Satan, who seeks by all means to devour us, is overcome by watchfulness and faith.

People's New Testament

5:8 Be sober. Sobriety is necessary to vigilance.

Be vigilant. Wide awake and watchful. The reason follows. An enemy is ready to spring upon them.

The devil, as a roaring lion, walketh about, seeking whom he may devour. He goeth about as the lion, seeking for prey. The lion while hunting only roars when it springs. So the devil is stealthy and does not give warning of his approach.

Wesley's Notes

5:8 But in the mean time watch. There is a close connexion between this, and the duly casting our care upon him. How deeply had St. Peter himself suffered for want of watching! Be vigilant - As if he had said, Awake, and keep awake. Sleep no more: be this your care. As a roaring lion - Full of rage. Seeking - With all subtilty likewise. Whom he may devour or swallow up - Both soul and body.

Jamieson-Fausset-Brown Bible Commentary

8. Peter has in mind Christ's warning to himself to watch against Satan, from forgetting which he fell.

Be sober . vigilant-"Care," that is, anxiety, will intoxicate the soul; therefore be sober, that is, self-restrained. Yet, lest this freedom from care should lead any to false security, he adds, "Be vigilant" against "your adversary." Let this be your "care." God provides, therefore do not be anxious. The devil seeks, therefore watch [Bengel].

because-omitted in the oldest manuscripts The broken and disjointed sentences are more fervid and forcible. Lucifer of Cagliari reads as English Version.

adversary-literally, "opponent in a court of justice" (Zec 3:1). "Satan" means opponent. "Devil," accuser or slanderer (Re 12:10). "The enemy" (Mt 13:39). "A murderer from the beginning" (Joh 8:44). He counteracts the Gospel and its agents. "The tempter."

roaring lion-implying his violent and insatiable thirst for prey as a hungry lion. Through man's sin he got God's justice on his side against us; but Christ, our Advocate, by fulfilling all the demands of justice for us, has made our redemption altogether consistent with justice.

walketh about-(Job 1:7; 2:2). So the children of the wicked one cannot rest. Evil spirits are in 2Pe 2:4; Jude 6, said to be already in chains of darkness and in hell. This probably means that this is their doom finally: a doom already begun in part; though for a time they are permitted to roam in the world (of which Satan is prince), especially in the dark air that surrounds the earth. Hence perhaps arises the miasma of the air at times, as physical and moral evil are closely connected.

devour-entangle in worldly "care" (1Pe 5:7) and other snares, so as finally to destroy. Compare Re 12:15, 16.

Matthew Henry's Concise Commentary

5:5-9 Humility preserves peace and order in all Christian churches and societies; pride disturbs them. Where God gives grace to be humble, he will give wisdom, faith, and holiness. To be humble, and subject to our reconciled God, will bring greater comfort to the soul than the gratification of pride and ambition. But it is to be in due time; not in thy fancied time, but God's own wisely appointed time. Does he wait, and wilt not thou? What difficulties will not the firm belief of his wisdom, power, and goodness get over! Then be humble under his hand. Cast all you care; personal cares, family cares, cares for the present, and cares for the future, for yourselves, for others, for the church, on God. These are burdensome, and often very sinful, when they arise from unbelief and distrust, when they torture and distract the mind, unfit us for duties, and hinder our delight in the service of God. The remedy is, to cast our care upon God, and leave every event to his wise and gracious disposal. Firm belief that the Divine will and counsels are right, calms the spirit of a man. Truly the godly too often forget this, and fret themselves to no purpose. Refer all to God's disposal. The golden mines of all spiritual comfort and good are wholly his, and the Spirit itself. Then, will he not furnish what is fit for us, if we humbly attend on him, and lay the care of providing for us, upon his wisdom and love? The whole design of Satan is to devour and destroy souls. He always is contriving whom he may insnare to eternal ruin. Our duty plainly is, to be sober; to govern both the outward and the inward man by the rules of temperance. To be vigilant; suspicious of constant danger from this spiritual enemy, watchful and diligent to prevent his designs. Be stedfast, or solid, by faith. A man cannot fight upon a quagmire, there is no standing without firm ground to tread upon; this faith alone furnishes. It lifts the soul to the firm advanced ground of the promises, and fixes it there. The consideration of what others suffer, is proper to encourage us to bear our share in any affliction; and in whatever form Satan assaults us, or by whatever means, we may know that our brethren experience the same.

Matthew Henry's Whole Bible Commentary

Verses 8-9

Here the apostle does three things:-

I. He shows them their danger from an enemy more cruel and restless than even the worst of men, whom he describes,

1. By his characters and names. (1.) He is an adversary: "That adversary of yours; not a common adversary, but an enemy that impleads you, and litigates against you in your grand depending cause, and aims at your very souls." (2.) The devil, the grand accuser of all the brethren; this title is derived from a word which signifies to strike through, or to stab. He would strike malignity into our natures and poison into our souls. If he could have struck these people with passion and murmuring in their sufferings, perhaps he might have drawn them to apostasy and ruin. (3.) He is a roaring lion, hungry, fierce, strong, and cruel, the fierce and greedy pursuer of souls.

2. By his business: He walks about, seeking whom he may devour; his whole design is to devour and destroy souls. To this end he is unwearied and restless in his malicious endeavours; for he always, night and day, goes about studying and contriving whom he may ensnare to their eternal ruin.

II. Hence he infers that it is their duty, 1. To be sober, and to govern both the outward and the inward man by the rules of temperance, modesty, and mortification. 2. To be vigilant; not secure or careless, but rather suspicious of constant danger from this spiritual enemy, and, under that apprehension, to be watchful and diligent to prevent his designs and save our souls. 3. To resist him stedfast in the faith. It was the faith of these people that Satan aimed at; if he could overturn their faith, and draw them into apostasy, then he knew he should gain his point, and ruin their souls; therefore, to destroy their faith, he raises bitter persecutions, and sets the grand potentates of the world against them. This strong trial and temptation they must resist, by being well-grounded, resolute, and stedfast in the faith: to encourage them to this,

III. He tells them that their care was not singular, for they knew that the like afflictions befel their brethren in all parts of the world, and that all the people of God were their fellow-soldiers in this warfare. Learn, 1. All the great persecutions that ever were in the world were raised, spirited up, and conducted, by the devil; he is the grand persecutor, as well as the deceiver and accuser, of the brethren; men are his willing spiteful instruments, but he is the chief adversary that wars against Christ and his people, Gen. 3:15; Rev. 12:12. 2. The design of Satan in raising persecutions against the faithful servants of God is to bring them to apostasy, by reason of their sufferings, and so to destroy their souls. 3. Sobriety and watchfulness are necessary virtues at all times, but especially in times of suffering and persecution. "You must moderate your affection to worldly things, or else Satan will soon overcome you." 4. "If you would overcome Satan, as a tempter, an accuser, or a persecutor, you must resist him stedfast in the faith; if your faith give way, you are gone; therefore, above all, take the shield of faith," Eph. 6:16. 5. The consideration of what others suffer is proper to encourage us to bear our own share in any affliction: The same afflictions are accomplished in your brethren.
