“There is a God shaped vacuum in the heart of every man which cannot be filled by any created thing, but only by God, the Creator, made known through Jesus”.
When our reality crashes down on us too hard, because of this sense of needing something outside of us, given our fallen nature, we tend to fill that void with unhealthy things -- things like food...or alcohol...or sex...or choose-your-vice here. Such things may take our eyes off our reality for a short time; long term, however, these vices will have disastrous results. No, God has created you in such a way, that He is the only one who can fill that void.
God is abstract who gives meaning to the stark realities of life.
