There is no other worldly transformation to give meaning to life. The only meaning we can hope to derive from our earthly existence results from the acts of love we share with other people. Life, not death, possesses meaning. Everything else we do will be forgotten. Time moves on.
Memory is erased.
Our love, though, is what will link us to the living. Although the world is not governed by an omniscient and omnipresent God, we can still find meaning in the world. We possess both the freedom and the ability to chose how we want to live. Those of us remaining the land of the living need to take advantage of our opportunities to love while they are still available to us. Because the opportunity to love can be taken from us every so quickly.
