To help one grandchild if I couldn't afford to help all the same

[Jumpyy]

One of my grandchildren is going through a horrible time with fertility issues. She's been told that IVF is probably her only option which she and her husband cannot really afford.

She is suffering badly because of this, I believe very depressed and just not in a good place.

I have some money and I would like to give it to them for the treatment.

I have 4 other grandchildren most of whom are younger and (although unlikely), I probably wouldn't be able to afford to do the same for them or give them a similar amount at the same age, if I do this now.

WWYD? I don't want to see her suffering if I can help.

If you went down the 'giving' route, this is a great representation, that I often used with pupils in school, to explain why some people need more than others to get to the same point.

What’s the relationship like between the grandchildren?

My grandparents didn’t have any money at all. I’m one of 16 grandchildren. But if they’d been able to help any one of us in the way you’re describing I would have been all for it.

I didn't mean the prodigal son.

I take a meaning of the parable of the workers in the vineyard to be happy with your own lot, rather than be jealous of somebody else's.

It has a more specific meaning that it doesn't matter how long you've been a believer, the reward is the same.

In any case, I don't think it's relevant to apply parables to the OP's situation or her relarives.

But, if you're going to, then it's the prodigal son, which has the religious meaning that people who leave God can still go back and be welcomed.
But it's also of notice, and in relation to the OP, that the father split his assets equally, but then helped one of them when he needed to be helped and his brother was encouraged to be kind and not jealous.

Having said that, the vineyard parable could also be interpreted as in eldest children/relatives being treated the same as the youngest.
It was the eldest who complained about not getting as much as the younger, but the owner gave them the same. Which wouldn't be the case with the OP giving an older child something that she can't give the youngest and she doesn't know if they'll need it.

This is the problem with the Bible. You can (almost) always find something to justify your pov.
