We're all prone to a "glass half full" or "glass half empty" tendency, aren't we?
Neither is necessarily right or wrong in itself. There truly requires a balance. Constant negativity (or as I like to call it, the Eeyore personality!) isn't much fun to be around. But neither is the eternally optimistic "Pollyanna". Sometimes, we just need a friend to sympathize and say "You're right! That totally sucks!" And other times we need a friend to encourage us and say "It's really not that bad."
Instead of leaning to either extreme, we should strive to keep the TRUE perspective - meaning, God's perspective. It's always right, no matter the situation.
When Goliath came against the Israelites, the soldiers all thought, "He's so big we can never kill him." David looked at the same giant and thought, "He's so big I can't miss."
A shoe manufacturer who decided to open the Congo market sent two salesmen to the undeveloped territory. One salesman cabled back: "Prospect here nil. No one wears shoes." The other salesman reported enthusiastically, "Market potential terrific! Everyone is barefooted."
During WWII General Creighton Abrams found himself and his troops surrounded on all sides. With characteristic optimism, he told his officers, "For the first time in the history of this campaign, we are now in a position to attack the enemy in any direction."
See what I mean? Perspective.
God doesn't call us to be naïve and constantly stuck in denial. But neither does He call us to run around screaming "the sky is falling!"
He calls us to trust in Him when we see giants and impossible situations. Trust in Him when we see a bleak future or failure or lack of opportunity. Trust in Him when our resources run dry and our creativity is gone and our hearts are broken. Trust in Him when we can't see in front of our face, much less the big picture.
Philippians 4:6 Fret not about anything, but in everything, by prayer and supplication with thanksgiving, let your requests be made known unto God.
He sees it all. I promise. And He cares. He has a plan and a purpose for your future. And it's for GOOD and for His glory. Even when all you see are giants with really big swords.
So don't worry about whether the glass is half full or half empty or if you even have a glass in the first place.
Trust in Him and His 20/20 vision :)
