God didn't intend for there to be suffering, remember it was the consequence of disobedience against God.
When people (Adam and Eve in the first instance) spoilt it, everything changed.
God says that He sorrows when we do, but that although we can't expect heaven on earth, He will give us comfort in the hard times. He didn't pretend any different.
I like Ecclesiastes where it says:
There is a time for everything,
and a season for every activity under the heavens:
2 a time to be born and a time to die,
a time to plant and a time to uproot,
3 a time to kill and a time to heal,
a time to tear down and a time to build,
4 a time to weep and a time to laugh,
a time to mourn and a time to dance,
5 a time to scatter stones and a time to gather them,
a time to embrace and a time to refrain from embracing,
6 a time to search and a time to give up,
a time to keep and a time to throw away,
7 a time to tear and a time to mend,
a time to be silent and a time to speak,
8 a time to love and a time to hate,
a time for war and a time for peace.
It's so true! But don't get me wrong, I have shaken my fist at God when I FEEL like He's got it all wrong (there go those unreliable feelings again!) but sometimes, in hindsight, we can see that suffering changed us into a deeper, more understanding person.
You can always tell a person who has suffered. They usually change to either become bitter or better.
