From my own experience of living without God for years and finally coming to be saved in 2004.  I have grown so much in patience, compassion, and loving others- - even those "difficult" people we all know.... hehe...But honestly knowing Jesus and having a very personal walk with Him has brought an extreme amount of peace to me, and I tend to be an anxious/worrier type of person.  Used to be very easily upset over, trying to schedule everything, just so and having everything orderly -heaven forbid- something pop up unexpected.  Now I'm okay because I know God will never give me more than I can handle and ultimately my day is all in His loving hands.  He will take care of me and provide all that I need, it may not always be what I want, but it is always enough.  So I will just take a *Breath* and say, "Thank you, Jesus."  And move on.....
