There is no “symphony” of Christ with Belial. When we try to harmonize them we have not concord but discord. To be a friend of the world is to be the enemy of God (Jas. 4:4), and if we love the world, the love of the Father is not in us (I Jno. 2:15).
We are not to effect a truce between Christ and Belial. We are out to issue an ultimatum: “Choose ye this day whom ye will serve.”
It is never Christ and. It is always Christ or. “He that is not with me is against me.”
