It would have been great to have you me in the time from Xmas '74 to mid February '75 when we had two kids dying per week in the PICU.
"Hey people, The only reason you're feeling bad about losing your child is that you don't think properly. After all, Scripture says, '... as he thinketh in his heart, so he is.' So chin up. Your suffering at the loss of your child is just faithlessness."
Personally, I wouldn't have the nerve to try that on somebody in REAL pain.
But, for all that, it's not all entirely bad. We are obliged to conclude, I think, the Jesus was happy on the cross.
