I wager we avoid that kind of love because it boils down to "sacrifice yourself for the good that's outside you". In human terms it's something like parents sacrificing themselves for their children, or friends sacrificing themselves for their friends[1]. Losing something painfully that cannot be replaced in the world. A world where we have all the time, money, internet to distract us from hardship & suffering that brings us closer to goodness.
I personally didn't believe in God until I received a tiny part of his love for myself.
