All hell is arrayed against us taking hold of eternal life. Therefore we must fight to keep our faith in God firm. We must fight to keep the falsehood of Satan, designed to destroy our faith, from deceiving us. We must also fight the falsehood of the evil one which penetrates our society.
Much of our society is given over to advancing God-denying socialism. Many want to throw off all moral restraints that hinder them from doing the evil they desire to do. We must continue to preach the truth and live it out in the face of all of this, to drive back evil in society.
Yes, we must fight the good fight of faith while maintaining the joy of the Lord through seeking God and fellowshipping with him.
