One day a flight attendant wanted to go on a trip and she was fortunate to receive from her employer a free seat that was available in first class. At no cost to her, she was able to fly to Europe. During the flight an emergency occurred on the airplane that made it so that they were in need of another flight attendant. She raised her hand and let them know she was a flight attendant, and even though she was on vacation taking a trip to Europe, she expressed that she would be glad to serve as the additional help that was needed. She was not serving to get to Europe; that had already been taken care of. It was part of the package of her being a flight attendant for the airline. But she had no problem serving on the airplane either, because she was grateful for the benefit to be able to ride to Europe at no cost to her. So, her service was joyful and not compulsory.
Unfortunately, today many people are serving Christ in order to earn brownie points to try and earn their salvation, instead of serving Christ out of the overwhelming joy of the free ride. Christians, God wants your service not as validation for your salvation. He wants your service out of your joy for the assurance of your salvation.
“Therefore if you have any encouragement from being united with Christ, if any comfort from his love, if any common sharing in the Spirit, if any tenderness and compassion, then make my joy complete by being like-minded, having the same love, being one in spirit and of one mind. Do nothing out of selfish ambition or vain conceit. Rather, in humility value others above yourselves, not looking to your own interests but each of you to the interests of the others. In your relationships with one another, have the same mindset as Christ Jesus: Who, being in very nature God, did not consider equality with God something to be used to his own advantage; rather, he made himself nothing by taking the very nature of a servant, being made in human likeness. And being found in appearance as a man, he humbled himself by becoming obedient to death— even death on a cross!”
(Philippians 2:1-8 NIV)
