It isn’t popular to portray the God of Jesus as the God of judgement, we cannot escape the facts though:

The invaders charge. They climb barricades. Nothing stops them.
Each soldier does what he’s told, so disciplined, so determined.
They don’t get in each other’s way. Each one knows his job and does it.
Undaunted and fearless, unswerving, unstoppable. They storm the city,  swarm its defenses, loot the houses, breaking down doors, smashing windows. They arrive like an earthquake, sweep through like a tornado.
Sun and moon turn out their lights, stars black out.
God himself bellows in thunder as he commands his forces.
Look at the size of that army! And the strength of those who obey him!
God’s Judgment Day—great and terrible. Who can possibly survive this? Joel 2:7-11 (The Message)

We may shy away from such imagery in the Bible but here it is. The invading army is carrying out the orders of its commander in chief. We see the devastation that accompanies them and have to question, with the Prophet, ‘Who can possibly survive this?’

For those who seek to follow Jesus the action of God in the physical world as he carries out his judgement may be the same. There is nothing to say that people of faith are not caught up in the same dramatic events in history that everyone else is. The difference comes when we see the commander of the invading army. Is he our commander too? Are his actions just in our eyes and are we willing to see beyond the devastation caused in the physical world to the promise he holds. No one who trusts in Jesus Christ has to fear judgement. Anyone who holds to the way of faith in him can rely on the amazing saving grace of God. The book of Revelation says, ‘ I saw another Angel soaring in Middle-Heaven. He had an Eternal Message to preach to all who were still on earth, every nation and tribe, every tongue and people. He preached in a loud voice, “Fear God and give him glory! His hour of judgment has come! Worship the Maker of Heaven and earth, salt sea and fresh water!” Revelation 14:6 (The Message)

While God may act in fearful ways, we are called to worship him eternally. Although he may judge the world in ways we do not fully understand, from it he will bring about his salvation.

Almighty God, although I may fear the works of your hand that I do not fully understand, I will trust in you and worship you with heart, soul, mind, and strength as long as I live. Amen.
