The proof of a living faith is seen when it is passed on intact from generation to generation. It is true to say that the fruit of the Holy Spirit is evidence of faith: brotherly love, peace of mind and peace in word and action, joy, thankfulness, contentment, humility. But when this is not passed on from one generation to the next, it would appear that something was missing.
Tradition is important. The ancient landmarks of the faith were placed for a reason. But if the next generation doesn’t understand why they were placed or just what they mean, they are apt to get their bearings from the things that seem most important in their day.
The ancient landmarks may have been interpreted in a way that met the needs of the older generation, but no longer meets the needs of the younger. Yet the basic principles remain unchanged. These principles must be continually taught, always in a way that can be understood and will meet the needs of upcoming generations. A rigid adherence to a form of words or practice will not do that.
The new birth is important. There must be a genuine repentance for the sins of the past life and evidence that a new life has begun. This would include love for everyone, new priorities in life, carefulness to avoid things that have led to the sins of the past, and a desire to make right whatever harm may have been done to others.
The danger is to mistake the experience for the change that is needed. To tell a dramatic, heart-touching experience is not proof the heart has really been changed.
Knowledge of the Bible is important. But it needs to be studied to establish a foundation for my life, not to prove a point with somebody else. it is a danger sign when one has a proof text handy for most any discussion, but can’t explain what that text means in the language of everyday life.
A living faith does not have to be loud, but it should not be silent. A living faith will be modest, but should never run from a challenge. A living faith will make a difference at church, at home, at school, at work, on vacation, and especially in those times when no one is looking.
It is best for children to grow up in a home where parents are deeply committed Christians. But it is not enough and it is not a guarantee that the children will catch their parents faith. It is far better to grow up among a united group of believers who live out their faith in all aspects of everyday life. The spiritual heritage is much more important than the family heritage. This is what allows the upcoming generation to catch the faith of their elders and then to pass it on to the next generation.
