Because of the quid pro quo nature of romantic love, we sometimes expect that if we give more and more to our partner, then we will receive more and more in reciprocation. This is not true. Divine love is selfless love. It is love regardless of gender, of race, of age. It is seen in familial and religious love, platonic love.
Divine love has no physical representation.
Divine love requires no response, no reciprocation. It has no limit. Two may share divine love without any other form of love. They are soul-mates. This instance of divine love cannot be created it either exists or does not.
