My visit to the dentist was only painful to my wallet. Without proper care and attention decay would set in. The job of my dentist is to make my teeth as perfect as they can be.
As I sat in the chair I realised how like Christians teeth are.
Without care and attention sin will take hold and we are no longer beautiful and useful to God. He can take away our sin but it is at a cost to Him. Jesus died for our decay.
To eat with one tooth on its own is not very effective, but a mouthful of good teeth makes eating a pleasure. One Christian alone is not very useful, but a group working together is an effective way of telling Good’s good news.
