Or, to say it another way . . . On one occasion Jesus said, Don't cast your pearls before swine less they trample them underfoot and then turn and rend you.
I think he meant that it's not so much that smart, good, resourceful me has these wonderful, precious things to share - aspects even of myself, included - and that someone else is just too dumb or piggish or priggish to appreciate 'my pearls' - of wisdom or opinion or some other precious gift.
It's more that, well - pigs don't eat pearls ! - and so I need to figure out what it is they do need, if I'm to offer anything, or be anyone, helpful. What would be nourishing, appreciated, precious to them?
Some may 'trample underfoot' things, people (myself included) I think precious, worthwhile, worth something at least - because I'm offering what they perceive they do not need or want. They are likely quite unaware of any hurt I may feel to their response.
Some may 'turn and rend' me because they are still hungry but I've not given what they really need or desire. Maybe I don't have what they need; maybe they're finding it somewhere else - and will keep looking, thankyou.
A parent, a teacher, an employer, a pastor seeks to find ways, means, gifts that will truly nourish and nurture another, based on an adequate and accurate assessment of their child, student, mentee, employee. So also - I must find out what I can best and most helpfully give (if appropriate to do so at all), assessing whose need it is really, mine or another's before I cast forth my gift.
