The gospel of peace is not to be understood with the teaching of the worldwide peace. This is the peace is that is from God, and cannot be match with the false peace that the world claims they are teaching. This is a peace that comes from the grace and mercy of God. A peace that comes from when you feel down and out, but you comes into God with an open heart and mind and you feel an inner peace. Put on the whole armor of God, that you may be able to stand against the wiles of the devil. For we wrestle not against flesh and blood, but against principalities, against powers, against the rulers of the darkness of this world, against spiritual wickedness in heavenly places.
