I obtained an old book entitled 'Take off your Shoes' by Michael Griffiths, which was published by OMF in the Seventies. It is about missionary work in Japan.
I saw this book six years ago,in the secondhand section of a Christian bookshop. I did not buy it, but it did make me contemplate the thought of being a missionary in Japan. I managed to find a secondhand copy on the internet whcih I received today.
Being written in the Seventies, it is probably out of date, but I feel I would really like to read it.
