Hi John and Doves,
Almighty God has been prompting me to read the 3 chapters of Joel. I will go into how He has prompted me in a later post. Read through Joel 2 in the link. Read it carefully. The army that never breaks ranks and devours everything with fire is not some alien/robotic army. It is, in fact, the LORD's army. For a start, Joel 2 is about the Day of the Lord. The army's appearance is like horses. The nations panic and turn deathly pale. They are terrified. Why? Because there is no escaping this army of the LORD.
Reading through the 3 chapters of Joel - and especially Joel 2 - I have come to the understanding (after much prayer) that the rapture must have happened just before the events in Joel 2 unfold. Think about it.....Bible believing Christians would not be terrified at the sight of the LORD's armies. We would be beside ourselves with joy. The left-behind idolators will be terrified at the sight of this mighty army. This is when they scramble for their caves and underground bunkers as described in Revelation.
Please come soon, LORD Jesus.
