2 Corinthians 5:7

We live by faith, not by sight.

(v7, NIV)

Some people live by sight. They live by what they see. If they can't see it then they can't explain it and therefore it is not what they live by. It's the mentality of "I'll believe it when I see it". If it is our day to day living that people see on this earth that is visible to their eyes, that is what they may live by. However, we live by faith. Our faith is in our God who created this earth. I guess it's a broader perspective because God can see this whole earth and beyond. There may be powerful telescopes and some spaceships we've sent out into space to see beyond the bounds of our planet, but God can see all. Since we are not limited to living by what we see, the way we live is definitely different. We live knowing that there exists a life after death. This puts our tent-like dwelling on earth into perspective.

for we walk by faith, not by sight.

(v7, ESV)
