"Finally, be strong in the Lord and in His mighty power. Put on the full armor of God, so that you can make your stand against the devil’s schemes. For our struggle is not against flesh and blood, but against the rulers, against the authorities, against the powers of this world’s darkness, and against the spiritual forces of evil in the heavenly realms.
Therefore take up the full armor of God, so that when the day of evil comes, you will be able to stand your ground, and having done everything, to stand. Stand firm then, with the belt of truth buckled around your waist, with the breastplate of righteousness arrayed, and with your feet fitted with the readiness of the gospel of peace. In addition to all this, take up the shield of faith, with which you can extinguish all the flaming arrows of the evil one. And take the helmet of salvation and the sword of the Spirit, which is the word of God.
Pray in the Spirit at all times, with every kind of prayer and petition. To this end, stay alert with all perseverance in your prayers for all the saints. Pray also for me, that whenever I open my mouth, words may be given me so that I will boldly make known the mystery of the gospel, for which I am an ambassador in chains. Pray that I may proclaim it fearlessly, as I should." Ephesians 6:10-20
Evil has been carried out against devout Christians since the days of Christ, so it should come as no surprise to anyone. In the days of the Apostle Paul the Saints of the Church dealt with the very evil we are talking about and so did the other Saints of the Church. Steven was stoned to death for his faith. Peter and Paul were both martyred in Rome about 66 AD, during the persecution under Emperor Nero. Paul was beheaded. Peter was crucified, upside down. Andrew was crucified in Greece, Thomas went to India as a missionary and was pierced to death by four soldiers. Philip went to Asia as a missionary where he was put to death by the Roman Pro-counsel. Matthew was stabbed to death in Ethiopia, Bartholomew was martyred for his preaching in Saudi Arabia, James travelled to Syria where he was stoned and then clubbed to death, Simon the zealot went to Persia where he was stoned, then clubbed to death, Matthias was burned to death in Syria, and John was the only apostle who died of natural causes in his old age.
I have written about this many times:
and more. Remember then, to put on your armor, and be strong in the Lord.
