Revelation 19:14 And the armies in heaven, clothed in fine linen, white and clean, followed Him on white horses.
Who are these armies in heaven? All the saints! We are given garments of righteousness by Christ. We dont get clean linens by our own righteousness. We will be following Jesus back down to earth on white horses, symbolic to conquering the enemies. Side note, we know there are horses in heaven, Im pretty sure other animals will be there, but I will just enjoy being suprised. I cant imagine heaven without them, but we will surely see.
