‘Well then, every scribe who becomes a disciple of the kingdom of heaven is like a householder who brings out from his storeroom things both new and old.’ Mt 13:52
Every tree, even if it is over a hundred years old, puts out new growth in the spring time. Its leaves take fresh energy from the sun and its roots are watered by the rain. Similarly for human beings, we are always growing and developing, learning new things and adapting to a changing world. Who could have predicted 2020? But we have the capacity to change our lives in changing times.
The same is true of faith, it needs to be always growing, always putting out new green leaves.
An old mature tree has reserves of strength to carry it through hard times. It can be the same for us. Our faith is old, Jesus Christ is the same yesterday, today and for ever. But it needs to be alive in the here and now. When we try to live out our faith in this 21st century world, we need things both new and old.
