Is your friend expecting an untimely demise? How old is his son? To what extent has he already raised him in "the truth"? I assume he made you [de facto] godparents when you were active JW's. Since he knows your current inactive status, I'm wondering why he would even ask you something like that. If he's really that concerned, maybe he should ask someone else to care for his kid in the event something happens to him.
Maryjane - This is my brother in law. His son (my nephew) is now almost 13 years old. Like I said, his father has always been regular with meetings and service, but now wants to do more. When they asked us to be the guardian, we were irregular, starting to fade, but because we live in different cities, they don't know just exactly how much. My hubby told him he gets to meetings when he can (which is once a year). I don't think he's expecting an untimely demise, but is just looking out for the best interests of his child, as any parent would do.
