And it is right here—in the fact that no human ever is perfectly happy in this life—that we have one of our proofs for the existence of everlasting happiness beyond the grave. God, who is infinitely good, would not place in human hearts this desire for perfect happiness if there were no way in which that desire could be satisfied. God does not torture with frustration the souls whom he has made.
