Ever notice that in heaven there are different positions attained by the saints? There are kings, priests, and servants. Some saints are seen in close proximity to Christ round about the throne, while others stand before the throne. Some are with Christ when He receives His throne, and others are taken up out of great tribulation. There are those with crowns, and some with palms.

1 Corinthians 3:15 If any man's work shall be burned, he shall suffer loss: but he himself shall be saved; yet so as by fire.
Revelation 22:12 And, behold, I come quickly; and my reward is with me, to give every man according as his work shall be.
