How do christians view apostasy

[Jenny A]

What would you do if your child, who you had brought up strictly christian eventually rejected your god?

“Each one of us here today will at one time in our lives look upon a loved one who is in need and ask the same question: We are willing to help, Lord, but what, if anything, is needed? For it is true we can seldom help those closest to us. Either we don't know what part of ourselves to give or, more often than not, the part we have to give is not wanted. And so it is those we live with and should know who elude us. But we can still love them - we can love completely without complete understanding.”
― Norman Maclean, A River Runs Through It and Other Stories

That's lovely. And brownie points for quoting one of my "touch stone" books. Norman Maclean was a wise man.
