Perfect love has no basis except the nature of the lover. There is absolutely nothing inherent in humankind that should make God love us. For instance, God did not look into the future and see that you are going to do good then decide that he would love you. Loving is his nature; he is only acting consistent with himself. If that doesn’t make sense to the rational minds of Adam’s descendants, it is because such love is a divine thought and must be received by faith.
