Enlist

Rev 19:14
The armies of heaven were following him, riding on white horses and dressed in fine linen, white and clean.

I've come to realize, that although I have never registered to serve in our nations military, I am enlisted in the army. The armies of heaven... When we choose to follow Christ with our lives we become part of his heavenly army. Substitute your name for the word armies.

(Your name here) of heaven was following him, riding on a white horse and dressed in fine linen, white and clean. As a Christ follower we are in his army. Our uniform is the finest linen, of the brightest white. A battle has been fought on our behalf and we have been made clean and bright.

I've never been in the military but I do understand marching orders.
You will be my witnesses.
Go and make disciples.
Take care of widows and orphans and do not become corrupted by the world.

The you is plural, it includes all followers of Christ. We have our orders, time to march.
