Our word, enthuse, originates from the Greek word, entheos (en + theos…or “in God”), which means to be “divinely inspired, possessed by God.” Enthusiasm comes from enthousiazein meaning to “be inspired or possessed by God, be rapt, be in ecstasy.” Speaking in plain English, believers in Jesus Christ should be on fire as we abide/dwell in Him.
Let’s take a snapshot of what happened in the New Testament when God (Theos) invaded the lives of 3000 people who responded to an awesome sermon preached by Peter, a former fisherman and coward now transformed by the filling of the Holy Spirit in his heart:
In Acts 2:36-44 Peter declares, “’Therefore, let all Israel be assured of this: God has made this Jesus, whom you crucified, both Lord and Messiah.’ 37 When the people heard this, they were cut to the heart and said to Peter and the other apostles, ‘Brothers, what shall we do?’ 38 Peter replied, ‘Repent and be baptized, every one of you, in the name of Jesus Christ for the forgiveness of your sins. And you will receive the gift of the Holy Spirit. 39 The promise is for you and your children and for all who are far off—for all whom the Lord our God will call. 40 With many other words he warned them; and he pleaded with them, “Save yourselves from this corrupt generation.” 41 Those who accepted his message were baptized, and about three thousand were added to their number that day. 42 They devoted themselves to the apostles’ teaching and to fellowship, to the breaking of bread and to prayer. 43 Everyone was filled with awe at the many wonders and signs performed by the apostles. 44 All the believers were together and had everything in common.”
Peter’s “en(Theos)iasm” was electric and his sermon was delivered by the actual resurrected power of God the Holy Spirit living in him and through Him. Now, these folks who responded to Peter’s words were absolutely “turned on” by God because they were now en(Theos)ed. God was now living in them! Peter warned them in verse 40 above in plain language to “keep yourselves from the corruption of this world.” Live in the world but not of the world.
Galatians 5:24&25 states, “Those who belong to Christ Jesus have crucified the flesh with its passions and desires. Since we live by the Spirit, let us keep in step with the Spirit.” We throw off the corruption of this world and live by sharing life walking with God the Holy Spirit who resides in us. Ephesians 5:18 instructs us to “be constantly filled with the Holy Spirit.” If so, our life will be characterized by “en-Theos-iasm”, full of life!
