Book excerpt: Do you say 'yes' to requests when really you mean to say 'no'? Do you feel permanently trapped by your 24/7 lifestyle? While offering practical help to busy Christians, Tim Chester also opts for root-and-branch treatment: you need to deal radically with the things that are driving you. If you're busy because of the following; 'I need to prove myself'; 'Otherwise things get out of control'; 'I like the pressure/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.
