Joy supercedes happiness or unhappiness, comfort or discomfort. The natural discomforts that create spiritual deficit spur the acceptance of God's persistant offering of life filling love. The definition of life as it was designed to be experienced is not about performance or self worth, it is about love. No words in natural language have the power or ability to entirely describe it, just like that hole in every person's life that needs filling. That hole is in a dimension that coincides with I AM and they just happen to be the same size and volume.
Every human has a choice.
No God or Know God. Faith is the art of holding onto the things your reason has once accepted. For your moods will change. I know that full well. For as a Chrisitian I have had moods where the whole thing looked very improbable, but as a non-Christian I had moods in which the whole thing looked terribly probable.
