2 Corinthians 4:16-18
16 So we aren’t depressed. But even if our bodies are breaking down on the outside, the person that we are on the inside is being renewed every day. 17 Our temporary minor problems are producing an eternal stockpile of glory for us that is beyond all comparison. 18 We don’t focus on the things that can be seen but on the things that can’t be seen. The things that can be seen don’t last, but the things that can’t be seen are eternal.
