Without suffering there would be no compassion. It is through suffering that we all learn to care about one another and feel compassion towards them, it teaches us to truly love people and care for them.
A time of suffering is not a time to turn away from God, it is a time to become closer with God. In those times of suffering God is there for you, it is when you need Him most, yet it seems to be a time when people give up on Him. Why is that? If you believe in Him and praise Him, He will be there for you, and never leave your side. God tests us in many ways, but never gives us more than we are capable of getting through. Open your eyes and your heart to God, believe in Him and let Him carry you when you feel yourself falling.
