Someday you and I are going to stand in the presence of the holy Lord, and our life will be reviewed. At that time, our works will be judged, and we will be rewarded accordingly.
That is going to be a very solemn moment because some will suffer heavy loss, while others will receive great reward. I'm not taking about salvation here, because salvation is never a reward for services rendered-it's simply a gift offered to everyone who receives Jesus as Savior. But rewards are different. They are tied to service.
In the Bible, Jesus had a lot to say about the rewards that we will receive for serving. He also used some very strong words to describe the man who hid his talent instead of working to invest it. In the parable, his master called him a "wicked, lazy slave" and proceeded to take away what had been given earlier (Matt. 25:26).
The Lord also gave us another warning: He cautioned us not to perform Christian service in such a way that others will be certain to notice. When that happens, He says we lose our reward in heaven(6:1-6). Whatever may have been set aside for our benefit will be lost, and our total gain is nothing more than the recognition of others.
The best way to serve is out of love. The better you know God, the more you'll love Him and desire to serve Him. And the more you want to serve, the more He will honor your service. This leads to even greater love for Him, and the cycle will continue throughout eternity.
