Don't center your attention on what you can see in this natural, physical sense realm. Everything you see is temporal and subject to change. So, put your faith in the unseen eternal realm. The things which are eternal are not subject to change.
God's Word is eternal and it contains 7,000 promises to cover any circumstance you'll ever face. And, no matter what happens in this shifting, changing world you live in, those promises will forever be the same.
No matter how bad your body feels, the Word will always say, "By His stripes you were healed" (1 Peter 2:24). No matter how bad your bank book looks, the Word will always say, "My God shall supply all your need according to his riches in glory by Christ Jesus" (Philippians 4:19).
Don't settle for the meager existence the world says you can have. Lay hold of what the Word says you can have. Center your attention on the eternal truths of God and look not to the things which are seen. After all, they're subject to change!
