Romans 12:11 (NIV) Never be lacking in zeal, but keep your spiritual fervor, serving the Lord.
Enthusiasm is God’s energy in my spirit expressing itself through my mind, will and emotions. Another biblical term for enthusiasm is “zeal,” which is derived from a Greek word, zelos meaning “excitement of mind, ardor, fervor of spirit.” The opposite of enthusiasm is apathy.
The Bible commands every believer to be enthusiastic in the basic matters of Christian living. Some of the areas of Christian fervor include: loving others, prayer, good works and even repentance.
Enthusiasm is passionate devotion to the work of God. When I am enthusiastic, I am expressing the power of God’s working of God’s working in me. A famous missionary Jim Elliot said, “Wherever you are, be all there. Live to the hilt every situation you believe to be the will of God.” Enthusiasm turns ordinary actions into extraordinary achievements.
The Bible gives an example of ministers of the gospel who exuded enthusiasm: One of them was Apollos in Acts 18:24-25 “Meanwhile a Jew named Apollos, a native of Alexandria, came to Ephesus. He was a learned man, with a thorough knowledge of the Scriptures. 25 He had been instructed in the way of the Lord, and he spoke with great fervor and taught about Jesus accurately, though he knew only the baptism of John.” The other one is in 1 Corinthians 16:15 You know that the household of Stephanas were the first converts in Achaia, and they have devoted [literary, addicted] themselves to the service of the saints. I urge you, brothers. These people serve as examples for us who are in service for the Lord Jesus Christ. Regardless of our vocations and locations we should give whatever we do our all. Our lives and service should exude enthusiasm and passion, as a result of the outworking of God’s energy in us.
