When the enemy comes in like a flood, the Spirit of the LORD will lift up a standard against him.—Isaiah 59:19 JNN 132.1
I was shown that God’s true people are the salt of the earth and the light of the world. God requires of them continual advancement in the knowledge of the truth, and in the way of holiness. Then will they understand the coming in of Satan, and in the strength of Jesus will resist him. Satan will call to his aid legions of his angels to oppose the advance of even one soul, and, if possible, wrest it from the hand of Christ. JNN 132.2
I saw evil angels contending for souls, and angels of God resisting them.... Evil angels were corrupting the atmosphere with their poisonous influence, and crowding about these souls to stupefy their sensibilities. Holy angels were anxiously watching and waiting to drive back Satan’s host. But it is not the work of good angels to control the minds of human beings against their will. If they yield to the enemy, and make no effort to resist him, then the angels of God can do but little more than hold in check the host of Satan, that they shall not destroy, until further light be given to those in peril, to move them to arouse and look to heaven for help. Jesus will not commission holy angels to extricate those who make no effort to help themselves. JNN 132.3
If Satan sees that he is in danger of losing one soul, he will exert himself to the utmost to keep that one. And when the individual is aroused to his danger, and, with distress and fervor, looks to Jesus for strength, Satan fears that he will lose a captive, and he calls a reinforcement of his angels to hedge in the poor soul, and form a wall of darkness around him, that heaven’s light may not reach him. But if the one in danger perseveres, and in his helplessness casts himself upon the merits of the blood of Christ, our Saviour listens to the earnest prayer of faith, and sends a reinforcement of those angels that excel in strength to deliver him.... At the sound of fervent prayer, Satan’s whole host trembles.... And when angels, all-powerful, clothed with the armory of heaven, come to the help of the fainting, pursued soul, Satan and his host fall back, well knowing that their battle is lost.... And although they hate and war with one another, yet they improve every opportunity.... But the great Commander in heaven and earth has limited Satan’s power.—Testimonies for the Church 1:345, 346. JNN 132.4
Further Reflection: Have I brought my all to the battle with Satan? Have I resisted him? JNN 132.5
