“Entheos” in Greek is rendered literally “in God.” When you sense “enthusiasm” you are most accurately being in God with your heart and soul. When you are thoroughly jazzed about something – when something is exciting to the point of being giddy – you are most accurately experiencing entheos.
When you were first converted you no doubt had a sense of the entheos of God at various areas. Enthusiasm is the normal state of being for believers in Jesus. You were probably very excited about growing in your knowledge and awareness of God’s word for example. You felt a great hunger to know God through prayer and listening to his voice.
We have been designed by God to contain his Spirit not just in fullness but to an overflowing degree. Do you lack the entheos of God? Give him away and see the lights come on as others wake up to his love.
