The telephone has burnt many a dinner and disrupted many a family meal. Try to avoid phoning too late at night. Try and save money by calling at off-peak times, and avoiding unnecessary or unnecessarily long calls. Every penny saved on the phone is a penny more for the collection plate. Don't waste people's time.
Time is even more precious than money.
Don't feel the need to answer every call. A habit has grown up of answering the phone regardless of what you are doing. It is easy to sympathise with the child who drowned the phone in a bucket of water. Talking to God is far more important than talking to anyone else. Speaking of which, the Lord's Day is for the Lord and not for phoning family and friends.
