Isn’t God supposed to be good? Isn’t He supposed to love us? Does God want us to suffer? What if the answer to those questions is YES? See, I’m not sure that God particularly wants us to be happy.
I think He wants us to be able to love and be loved. He wants us to grow up.

I suggest to you that it is because God loves us that He makes us the gift of suffering. To put it another way, pain is God’s megaphone to rouse a deaf world.

You see, we are like blocks of stone out of which the sculptor carves the forms of men. The blows of His chisel, which hurt us so much are what make us perfect.
