Jesus gave us a glimpse of what we are waiting for as he proceeded through the furnace of affliction (Isaiah 48:10) on the road from the Crucifixion to the Resurrection. He did not give us a declaration about God. He gave us a demonstration of God.
Armageddon is here and now. We are not fighting for something in the hereafter. The battle is now. Now is the time to join Jesus in the scrum at the line of scrimmage in the Valley of Tears facing off against Evil toe to toe, cheek to jowl. Christianity is not a sport for spectators. Christians partake in the fray.
