Do you say 'yes' to requests when really you mean to say 'no'? Do you feel permanently trapped by your 24/7 lifestyle? Do you feel guilty when you look at the size of your email inbox? Do you ever wonder who hit the accelerator?

While offering practical help to busy Christians, Tim Chester also opts for root-and-branch treatment: it's not enough to slow down, or to simplify your lifestyle, you need to deal radically with the things what are driving you.

If you're busy because of the following:

• 'I need to prove myself'
• 'Otherwise things get out of control'
• 'I need the money'

Think again! At the root of our 'slavery' are serious misunderstandings, often reinforced by our culture. If we want to be free, then we need to counteract them with God's word. It's important to manage our time, but it's more important to manage our hearts.

God has promised his rest to all who are weary and burdened (Matthew 11:28). It's up to us to accept it.
