It’s hard to image a world with no war, no competition, no division, and no sorrow. For us, it might even be unimaginable. But, this is exactly the body God has created in Christ. This is exactly the body empowered by God with the Spirit. This is the beauty of humanity formed by God in creation.
Into a world that keep trying to escape the frailty of the human body, God chooses to send Jesus in the form of the human body. As such an incarnate being, Jesus becomes the model for the church.
Saying to another, God won’t give you more than you can handle seeks to write off each person as an individual who must bear such hardships on their own. There is no Biblical foundation to this.
