How can I define comfort?

As Pilgrim rightly states, we live in such a corrupt world so many evils and tragedies. Without knowing the comfort of God one could be overwhelmed and despair of such atrocities.

Comfort is knowing that nothing is out of His control. The promise that He preserves me in such a way that without the will of my heavenly Father, not a hair can fall from my head. To be able to trust Him in and through all things, this brings me great comfort along with the wonderful promise, I now have eternal life.

I love the answers to question 1.
