Hey Mino, how's it going?"But this is a God who does not want the joy and happiness of his sons."
No it isn't. God himself is the happiness of his sons. To be content in this world would be nice, yes, but it would be making do with a sort of synopsis of God's goodness. So, I dunno, God is more like Hamlet and this world is like the Cliff Notes. Perhaps more to the point, didn't your Dad ever get you to do something that you didn't want to do, but turned out to be a good idea after all? Like get out of bed and go to school in the morning? The difference is that we get to grow up into people whose intelligence approximates to that of their fathers, and because of our own experience and love know that we have to kick our own kids out of bed. But we don't grow up into God; instead he allows us sonship.
I tell you the truth, unless you change and become like little children, you will never enter the kingdom of heaven. Therefore, whoever humbles himself like this child is the greatest in the kingdom of heaven."It seems that the bad exists just to remind people to "call" God from time to time: kind of post-it !!!"
I can't imagine a more necessary post-it then. It seems to aptly sum up a Christian approach to natural evil, the type that would have confronted Adam and Eve had they never rebelled. Again, if we made do with the world when we could have God, we'd be fools. There's sin too of course, which is turning from love of God to love of the world, and that suffering comes from ourselves. I suppose what you really wonder is why we have to call God anyway.
[W]hat is man that you are mindful of him,
the son of man that you care for him?
You made him a little lower than the heavenly beings
and crowned him with glory and honor.
So God created man in his own image, in the image of God he created him; male and female he created them.
We maintain that we have a dignity which is absolutely bound up with being like God, with aspiring to be "perfect [...] as [our] heavenly Father is perfect." We also maintain that a part of this dignity is our ability to say no. We can say, "Screw you God, I don't want you." And there is beauty enough in the world for us to seek God, and ugliness enough for us to shun him.
"They will remind of him only when they have bad times!"
I expect you mean remember him. Well, it isn't true. Speaking personally, I'm telling you that I feel drawn to God not only when I'm suffering, but when I'm content and when I'm happy. Not all the time of course.
"Why sacrifice and sorrow have to lead to God and not joy and happiness?"
Well, I sort of accounted for this above, but I'll just restate briefly. a) Joy and happiness do lead to God actually b) It is only natural that a sense of the lack of God should inspire people to look for him.
"Never heard of Saint Francis?"
Well, I've heard of him. newadvent.org tells me there's at least eight though. Don't know anything much about them. Care to share?
