Optimism is looking at the bright side of things.
Why can we as Christians be optimistic?
Because “greater is He that is in us than he that is in the world.”
“If God is for us, who can be against us?
He who did not spare His own Son, but gave Him up for us all —
how will He not also, along with Him, graciously give us all things?”
If optimism has no basis, than it is just wishful thinking.
But as Christians we have a reason for thinking positively —
and that reason is God.
We can face the future with a smile as children of the King!
