Look my friend
it's simple
1-when u was in college You study the whole year...why???
because if u didn't study then u fail...
and if u study good u get rewarded
2-If u have a car then who made it?
there must be some one who create it..Right
Now as I'm Muslim and proud Thanks to God...He told us that we are here for a test (your life time)
If you choose the way of God the creator of every thing then u Win at the end (Heaven for eternity)
and if u didn't follow God way then U fail (HellFire for eternity)
That's all
I hope you win..
