But, you have to address the question, blessed by whom?
I prefer fortunate instead of blessed, because “blessed” implies that someone (God) did the blessing. If that’s the case, others weren’t blessed by God and that leaves us with a difficult question as to why.
Well, of course it is blessed by God! You don’t get human beings into your life off a roulette wheel!
As to the why…well, why choose David and not his older brothers? What was wrong with them? Why did Hannah only get a son after such a long wait, and then a son she knew belonged to God? Why are some of us chosen for this and others for that?
What ought to be noticed about women in the Bible is that many favorites show up with no reference to any children. Were Mary or Martha even married? What about the prophetess Anna? She was almost certainly childless. Tabitha probably had no children and no husband (Acts 9:36-42). There is no indication that Joanna and her husband, Cuza the steward, had any children. Priscilla and Aquilla are not mentioned as having a family.
The thing to notice is that the Bible only finds childlessness something to remark upon when the story is going to be about an older couple having a child. As far as I am aware, there aren’t any stories in which some evil woman is denied the joy of motherhood because God is punishing her. There are instances where a child with an irregular background is chosen for the special role…for instance, Perez in the line of David, whose mother was Tamar. David gained Bathsheba to be his wife by illicit means, and yet she bore Solomon. Generally speaking, however, the blessing of parenthood is just that, a free gift, not indicating that the parents deserved the blessings they are responsible for.
If you are a prophet, that is a gift, a blessing, and you are meant to handle that with an attitude of selflessness. If you are not a prophet, however, that doesn’t mean you have been cursed or left out or punished. Some are given this gift, and another one, that gift.
Children ought to be seen as blessings because as human beings they are made in the image and likeness of God. To be included in the procreation of a child is to have been included in the work of God.
Even if you gained that position by questionable means, the dignity of the child still sanctifies your place as a parent! If you are included in the circle of those responsible to care for a child, you have been given a sacred duty. It is not about you, though. It is about the great dignity of the child as a human being.
