Sometimes a "bigger picture" doesn't come to us but only after quite a period of time. It might be years even. I think most of us could say we understand this comment. There are times we may scratch our heads wishing we understood more completely what was happening. Maybe it was a death, job issues, financial challenges, health concerns.
Think about this statement: that it may take our "eyes of faith" to see the bigger picture. Each of us has an inner "faith" that allows us to see, not with our physical eyes, but with our spiritual "eyes". Each one of us is spiritual...not to be confused with religious. I could quote scripture and get into all that "religious" language but it is bigger than that, much bigger.
Sometimes when we have faced something huge, we are able to say to ourselves, and others, "it will be OK, no matter what". That is a statement that envisions something beyond the physical. The eyes of faith come from God, give us hope, and help to sustain us.

Yes, some days, I have sat down and cried, complained or kicked up some dirt but still very thankful, through it all still able to say, with eyes of faith, "it'll be alright". What do your "eyes of faith" help you see?
