Your calling is you are on planet Earth to put a telescope to the eye of the world. That’s why you exist. By your behavior, your parenting, the way you do your job, the way you worship, and the way you handle your things in life, everyone should read off of your life, “God is great.” That’s why you exist.
— John Piper, Why Am I Here?
Evangelicals such as Calvinistic Fundamentalist John Piper have a reductionist view of the world. In their minds, the sum of everything is the Christian God. Everything traces back to God. He is the Alpha and Omega, the first and the last, and the beginning and the end. God is in believers, they live their lives through him, and to him go all praise, honor, and glory. This God is a jealous deity, demanding that his followers worship him alone. Worshiping other Gods or no God at all brings upon people his wrath and judgment. This God demands that believers in him devote their entire being to him. He is not only the hub around which everything turns, he is also the rim, tube, and tire. Simply put, from birth through eternity, life is all about God.
After Evangelicals have spent their entire lives worshiping God, guess what they get to do after they die? More of the same.
