Re: 1-1/Wk1/Ch1: Simon the Leper
These examples illustrate the difficulties involved in discerning what to do about the leadership of the spirit. I would add the case of Gideon.
Gideon had the problem of knowing if the guidance was really from God, and so he put out a fleece. And then again. We are rarely given strong guidance that we know to be from God.
We can, prayerfully, get a sense of whether we are being tested for our willingness to act in a loving way, because such acts lead to more fruit. But some things we might interpret as tests of obedience are just difficult decisions.
Abraham's departure has gotten some attention over the years. Many commentators concluded that he was being led away from idolatry, and there is some indication of that in scripture. His sacrifice of Isaac is often taken as a dramatic statement by God that the commands of Moloch to kill children were not from the true God. I think those kinds of indications from context are often present when we think we might be undergoing testing for obedience.
I agree that obedience sometimes calls for taking actions whose specific purpose we cannot, or do not yet, understand. What I see too much of is people telling other people about what God is commanding them to do. That isn't present in any of the examples we have been looking at.
