Something to think about.
2 Vanity of vanities, saith the Preacher, vanity of vanities; all is vanity. Ecclesiastes 1:2
All of our efforts everything we strive for is a pointless, meaningless exercise without Christ. All of our altruistic pursuits will end up in the empty hole of nothingness.
If this life is all there is, then legacy is meaningless, and accomplishments are temporal at best. If the momentary is all there is, life is pointless without purpose. Without something more than our current existence life is no more than vanity. If vanity is all there is, then all we strive for is in vain. Life is then a pointless cycle of self-gratification, disappointment, self-gratification, disappointment, again and again, and again.
God is the only thing that breaks the cycle of hopelessness and pointlessness. God is the only thing that gives life meaning. God is the answer to vanity.
