...of fire

Despite the loud clamoring of the most hardened atheists, people have a sense that they were made for a purpose. I have yet to meet a person moving joyfully from place to place, reveling in life because it is meaningless.

It goes deeper. We aren't just on a quest to find the general purpose of humanity - though that has its place of course. Instead, we are looking for our unique place in the grand scheme of thing.
And when we find that God-given purpose, our souls are set on fire. We find the abundant life that Jesus spoke about.

Purpose: we hunger for one. When we have one we live. Without one we merely exist.
