Such a simple idea, but to save energy, turn your mobile (cell phone) off over night.
Genius. You wouldn't leave your TV on standby anymore, would you? So why leave your phone on?
Before you do, have look at your stored numbers/contacts.
You see I guess that a large proportion of those contacts are people you care about (based on the assumption that you are at a wealth level to use the internet recreationally to read blogs and are therefore likely to have a mobile phone and be connected to similar people who also have mobiles...)
If that's true, then why not use that list as a prayer list?
Go through the list and pray for a few? or perhaps send them an encouraging text? or maybe, just maybe you could ring them......?!
(and I write that to myself as much as anyone else!)
