Hi
She may not be ready to read anything 'apostate'. I have just read Captives of a Concept by Don Cameron (on this board) My friend will not read such apostate literature, so, a technique I intend to try is to:
1. make a list of the Biblical and Watchtower texts about how important it is to test everything, keep testing our faith, investigate our own religions etc. and try to get a commitment to carry out such a test, using only Watchtower publications.
2. Use the watchtower quotations and simple logic, in Captives of a Concept, to apply the test recommended by Fred Franz, to the organisation which Jesus allegedly inspected and appointed in 1919 based on pre-1919 spiritual food at the right time. Examine that spiritual food, then let the reader ask themself whether there remains the faintest chance that God has ever appointed or guided this organisation.
