What a surprise we're going to get when the Lord hands out the rewards!--As to who was really greatest! Some people serve unselfishly, sacrificially, utterly giving themselves to the utmost, and yet never getting the credit for it, and are virtually unknown!--But God has a great big Book, and it's known to Him, and He's writing it all down! And He'll reward everyone according to their works--whether they be good, or whether they be evil. (See Heb.6:10, 2Cor.5:10.) The Bible says, "Then they that feared the Lord spake often one to another: And the Lord hearkened, and heard it, and a Book of Remembrance was written before Him for them that feared the Lord and that thought upon His Name." (Mal.3:16)
At the Judgement Seat of Christ and the Marriage Supper of the Lamb someday soon, the Lord will greatly reward all those that had the faith and perseverance to stay in His school till class was dismissed.--So be faithful unto the end so that when you stand before Jesus one day soon, you will know you have done your job the best you can. Then you will "rejoice and be exceeding glad, for great shall be your reward in Heaven!" (Mat.5:12)--Not here always, but always There!
