We have an enemy is one of those things, and the people who succeed in this life and are praised by our converged media are themselves also converged. With evil.
Calvin notes that there are limits on what Evil can do. So we can pray, as Christ taught us, to be delivered from temptation and from evil. In this time, such prayers are essential.
16. But as the devil was created by God, we must remember that this malice which we attribute to his nature is not from creation, but from depravation. Every thing damnable in him he brought upon himself, by his revolt and fall. Of this Scripture reminds us, lest, by believing that he was so created at first, we should ascribe to God what is most foreign to his nature. For this reason, Christ declares (John 8:44), that Satan, when he lies, “speaketh of his own,” and states the reason, “because he abode not in the truth.” By saying that he abode not in the truth, he certainly intimates that he once was in the truth, and by calling him the father of lies, he puts it out of his power to charge God with the depravity of which he was himself the cause. But although the expressions are brief and not very explicit, they are amply sufficient to vindicate the majesty of God from every calumny. And what more does it concern us to know of devils? Some murmur because the Scripture does not in various passages give a distinct and regular exposition of Satan’s fall, its cause, mode, date, and nature. But as these things are of no consequence to us, it was better, if not entirely to pass them in silence, at least only to touch lightly upon them. The Holy Spirit could not deign to feed curiosity with idle, unprofitable histories. We see it was the Lord’s purpose to deliver nothing in his sacred oracles which we might not learn for edification. Therefore, instead of dwelling on superfluous matters, let it be sufficient for us briefly to hold, with regard to the nature of devils, that at their first creation they were the angels of God, but by revolting they both ruined themselves, and became the instruments of perdition to others. As it was useful to know this much, it is clearly taught by Peter and Jude; “God,” they say, “spared not the angels that sinned, but cast them down to hell, and delivered them into chains of darkness to be reserved unto Judgment,” (2 Pet. 2:4; Jude ver. 6). And Paul, by speaking of the elect angels, obviously draws a tacit contrast between them and reprobate angels.
17. With regard to the strife and war which Satan is said to wage with God, it must be understood with this qualification, that Satan cannot possibly do anything against the will and consent of God. For we read in the history of Job, that Satan appears in the presence of God to receive his commands, and dares not proceed to execute any enterprise until he is authorised. In the same way, when Ahab was to be deceived, he undertook to be a lying spirit in the mouth of all the prophets; and on being commissioned by the Lord, proceeds to do so. For this reason, also, the spirit which tormented Saul is said to be an evil spirit from the Lord, because he was, as it were, the scourge by which the misdeeds of the wicked king were punished. In another place it is said that the plagues of Egypt were inflicted by God through the instrumentality of wicked angels. In conformity with these particular examples, Paul declares generally that unbelievers are blinded by God, though he had previously described it as the doing of Satan. It is evident, therefore, that Satan is under the power of God, and is so ruled by his authority, that he must yield obedience to it. Moreover, though we say that Satan resists God, and does works at variance with His works, we at the same time maintain that this contrariety and opposition depend on the permission of God. I now speak not of Satan’s will and endeavour, but only of the result. For the disposition of the devil being wicked, he has no inclination whatever to obey the divine will, but, on the contrary, is wholly bent on contumacy and rebellion. This much, therefore, he has of himself, and his own iniquity, that he eagerly, and of set purpose, opposes God, aiming at those things which he deems most contrary to the will of God. But as God holds him bound and fettered by the curb of his power, he executes those things only for which permission has been given him, and thus, however unwilling, obeys his Creator, being forced, whenever he is required, to do Him service.
