13 Therefore take up the whole armor of God, that you may be able to withstand in the evil day, and having done all, to stand firm. 14 Stand therefore, having fastened on the belt of truth, and having put on the breastplate of righteousness, 15 and, as shoes for your feet, having put on the readiness given by the gospel of peace. 16 In all circumstances take up the shield of faith, with which you can extinguish all the flaming darts of the evil one; 17 and take the helmet of salvation, and the sword of the Spirit, which is the word of God
The world is full of warfare.
One could even say it's a world of warcraft (but only a few single guys living with their parents would say that)
Fight the good fight of faith.
Allah and any other that would exult their name against or over the Name of Jesus is an idol and will be toppled over when the King of Kings returns.
