I guess I'm thinking that happiness isn't that important. (As opposed to joy - I'm getting so good at Christianese!) No-one (as far as I know) spends their whole life being happy, and I honestly think that if I was happy all my life I would be a very shallow person - I think that, to start with at least, we need to be miserable, desperate, hopeless etc. to ever consider the important issues of life. How will I be confronted with my own (apparent) mortality if the shadow of death never falls across my path?
Equally, if life was one long haul of misery, unrelieved by encouragement or pleasure, I would probably be downtrodden and despondent. How could I understand hope if I never saw good things coming to those who waited?
So maybe hope is the thing - I have this kind of feeling, kind of like happiness and misery, which I think may be hope. And it's hope in God, and I'm sticking to it, and to him, no matter what anyone thinks, says or does. So there.
