Like many of my friends I am an eldest child, and, like many of them, am by nature mainly sensible and responsible. Also like many of them I have a younger sibling who has a more prodigal nature, is endless rescued by my surviving parent and causes me a mixture of anxiety and irritation. Compared with many, my younger sibling is not that extreme, but without my mother's unswerving compassion it might be a different story. Recently I've found myself getting annoyed by the situation, more that it is unfair to her than to me, and last night found myself identifying with the older brother in the Prodigal Son parable.
As I pondered this, and decided that the older brother was justified in being miffed, even if ungracious, I began to think about other older siblings in the gospels and decided we get a pretty bad press. It is generally assumed that Martha was the older sister and/or oldest sibling, and she is more remembered for her grumbling at Mary's perceived laziness than for her recognition of Jesus as Christ. In another short parable, the first (older?) son says he'll do what his father requires and then doesn't whilst the second (younger?) son says he won't and does. You'd kind of hope that Jesus, being an eldest, would have been a bit kinder to/about us - and maybe his treatment of Martha reflects an understanding of her role - but on the whole we don't come out of it looking too great.
So, the upshot is that I'll endeavour to be a little kinder in my attitudes to my sibling, accept more generously that my mother does something Godly and try not to sulk when I feel like the grumpy older brother!
