Faith, not seen and something hoped for.  It’s not always easy to trust in what you don’t see however it’s real easy to trust in what you do see.  But that’s not real faith.  Real faith is taking God at His word no matter what the circumstances look like or what you even feel like.  Either you trust God and take Him at His word or you don’t.  But that’s kind of a hard statement and not everybody is there yet.  That’s why God’s grace is so important.  He gives us the grace to learn to trust in Him, He gives us room to grow and learn how to take Him at His word.
