2 Corinthians 4:16
For which cause we faint not; but though our outward man perish, yet the inward man is renewed day by day.
Every night before I go to bed I take my cell phone and connect it to the battery charger and lay it on the night stand beside my bed. It usually wakes me up in the morning with a call or text. When I reach over and pick my phone up the screen has the words "fully charged" on display. It's ready to go, and through the day it is used a lot, calls, text, internet searches, and pictures.
It would be difficult to make it through the day without my phone. At the end of the day, it needs to be charged up again. I never one time thought about throwing it away because the battery was low, it's way to expensive.
The same goes for Christians, after a long day this body gets weary, and our faith may become weak, but we don't throw our faith away. We get recharged. The outward man may perish, but the inward man is renewed everyday by the Holy Spirit. An energized faith creates a energized life. If your running low get plugged in until you are fully charged.
