For the soul to be well, it needs to be with God.
The soul seeks God with its whole being. Because it is desperate to be whole, the soul is God-smitten and God-crazy and God-obsessed. My mind may be obsessed with idols; my will may be enslaved to habits; my body may be consumed with appetites. But my soul will never find rest until it rests in God.
The reason our souls hunger so is that the life we could be living so far exceeds our strangest dreams.
