The lawlessness we are witnessing in America is Satanic. Amillennialists cannot identify the main enemy, because they think Satan is bound up and sealed at this moment within the abyss. They undermine the main force behind lawlessness and thereby undermine the urgency of spiritual warfare.
As for postmillennialists, they believe that the world will increasingly become more righteous before Jesus returns. Do I need to say more? For obvious reasons, postmillennialism has fallen on hard times, as a disillusioned eschatology.
Your eschatology matters in these times. Many (American) Christians do not understand the terror that is soon coming around the corner. Get your spiritual house in order today, for tomorrow it will be too late.
