With sufficient time and determination, one can take on nearly any responsibility and do it justice. But if you take on too many, some or all suffer. Sometimes the distinction is obvious, but often less so.
One considers, of course, all the difficulties and inconveniences that might come with a a new responsibility -- but with enough sermons on the topic of sacrificial giving in one's head it is not always easy to determine the difference between, "This would be really hard, but a good thing to do," and "Danger! Danger, Will Robinson!"
Some of my Protestant friends at work have the tendency to say about nearly any topic, "I just prayed about it, and God told me that I should do X." I'm never sure whether this basically comes down to saying, "I prayed about it for a while and I thought that X might be a good idea," or if they've got a direct line to the Almighty that I'm missing.
God and I, I often feel, are not on quite such confidential terms as some others seem to be. There's a bit in Terry Gilliam's movie Time Bandits where the time traveling dwarves tell Kevin that they work for the Supreme Being.
Kevin: You mean God?I often feel rather the same way. God knows me much better than I know Him. And if our struggles through life are, from that perspective, rather more like the bumblings of the time bandits than Dante's sedate wanderings in the gloomy wood -- well, I wouldn't be surprised.
Fidgit: Well, we don't know Him that well. We only work for Him.
Which leaves one to wade through decision-making as best one can.
