It doesn't take wars for the "spirit of the anti-Christ" (as you call the devil) to deceive us. He is the master of deceit.
We live in the playground of Satan. We deal with him everyday of our lives - even the most devout of us has to be on guard, at all times.
It will be negligent and foolish for us to think that he makes mischief only during wars and upheavals. We need not look upon wars happening in far-away places, or in the past, to realise that Satan is indeed among us, and is using all kinds of ways and tools to deceive us.
All you have to do is read the news that's happening right here on our soil. The atrocities inflicted on hapless and innocent victims are happening everyday.
All sorts of anti-Christ activities occur as we speak. From murder to rape, etc.,
Anti-Christ-inspired movements need not have to be violent, either. An example would be the many different denominations of Christianity that corrupt the Scriptures to make it conform to whatever ideology that's being promoted....which only leaves so many confused about Christ.
Another example would be Christmas which had lost its true meaning to many, and non-believers (with the help of those who sit in power), seek to remove any reminders of Christ in our society.
Our faith is always under attack. It will always be. We are in a spiritual warfare as we speak.
EPH 6
The Armor of God
10 Finally, be strong in the Lord and in his mighty power. 11 Put on the full armor of God, so that you can take your stand against the devil’s schemes. 12 For our struggle is not against flesh and blood, but against the rulers, against the authorities, against the powers of this dark world and against the spiritual forces of evil in the heavenly realms. 13 Therefore put on the full armor of God, so that when the day of evil comes, you may be able to stand your ground, and after you have done everything, to stand. 14 Stand firm then, with the belt of truth buckled around your waist, with the breastplate of righteousness in place, 15 and with your feet fitted with the readiness that comes from the gospel of peace. 16 In addition to all this, take up the shield of faith, with which you can extinguish all the flaming arrows of the evil one. 17 Take the helmet of salvation and the sword of the Spirit, which is the word of God.
18 And pray in the Spirit on all occasions with all kinds of prayers and requests. With this in mind, be alert and always keep on praying for all the Lord’s people. 19 Pray also for me, that whenever I speak, words may be given me so that I will fearlessly make known the mystery of the gospel, 20 for which I am an ambassador in chains. Pray that I may declare it fearlessly, as I should.
