A mystery is something that is secret or impossible to fully understand. It also arouses curiosity through its obscure nature. The relationship of Christ to His church cannot be understood by anyone outside His kingdom. Even a person who has been saved finds it difficult to explain. He just knows that Christ has forgiven his sins and has washed them away by His blood. Those close to the new Christian also know that he is different, but they cannot understand why.
We live in a world where people expect an explanation for everything. Many suffer spiritually because they have not learned to live by faith. Faith opens the gate to the blessings of salvation. It allows us to experience the mysteries associated with redemption, even though we cannot explain them.
