Adi: When the Bible talks about woman being a suitable helper for man, it is precisely that. She is suitable because she is a woman. I don’t think it is saying that God has provided one woman most suited for man and his task is to find her out of so many women. Whomever he chooses, she is the one provided for him.
Grace: One who has prayerfully chosen believes that the one he has chosen is God’s choice for him. It is thus safe too to believe that one who is chosen and given is the one that best complements him, one that meets his needs, perhaps in ways not foreseen or even chosen.
