The old saying claims, "You do for love what you wouldn't do for money."
That is proven every Sunday in every church nursery when faithful volunteer workers change stinky diapers of infants who are not theirs. Yep, that's love!
When someone volunteers to sit in a nursery filled with stinky bawling babies, what are they looking for? Why do they do that? It isn't fun or pleasant. It doesn't do much for them.
Motive matters and when you are a nursery worker you are not doing it for the reward you are probably doing it for the relationships.
This verse states that "God is the rewarder of those who diligently seek Him".
Are you seeking God for a reward or are you seeking Him for a relationship? Is your faith based upon what you hope to get from Him or are you seeking to know Him?
Hebrews 11 is the Christian Heroes Hall of Fame (or Hall of Faith). What made these men and women exemplary was not just what they did, but what motivated them to do it.
Noah labored every day for over 100 years building something he had never built before to prepare for something he had never seen before! Why was he doing that? What reward was he seeking? He didn't get paid by the hour nor was he on salary. He not only had to pound the nails into the boards and seal then with pitch - he had to make the nails, he had to cut down the trees and draw the tar out of the trees. There were no Lowes or Home Depots in that day.
Noah wasn't in it for the reward. I believe he was in it for the relationship with God.
You could go through this list of great people and ask, "Were they after a reward or were they wanting a relationship?" I believe the answer would be the same, they wanted to please God through their obedience. And they did! They altered history! They changed the world! They changed lives!
In the end they discovered an amazing truth - God IS their reward! They found that what Who He is far exceeds anything we could ever receive from Him.
Are you seeking God for what you can get from Him? Are you after the reward more than you're after the relationship? God can't reward self-seeking. You run the risk of missing both the reward and the relationship - which, in fact, IS the reward!
