Good to see you again Mr Banks,
Funny you should talk of the Eithiopians. We had a very interesting program on our national television station last weekend that I only saw bits of unfortunately. It talked of the Eithiopian spirituality and how God speaks to them. They talked in detail of their belief in the Ark of the Covenant and one of the most fascinating things of all, was the number of dreams and visions they have with the Holy Spirit appearing to them.
One fascinating example was of a man who said the Holy Spirit appeared to him and told him to use his hands to carve churches out of rock, and they showed you him chipping away. He has created 6 churches like this as a witness to the world of the existance of the creator God.
I guess you have heard of the Eithiopian Eunoch in Acts chapter 8:26-40. He certainly knew the Old Testament and Philip was able to show him how Jesus was the one spoken of in the book of Isaiah as the suffering Christ, so they most certainly did have strong roots with the God of the Jews, and even came to Jerusaleum to worship in the Temple.
It makes a fascinating study and well, after hearing about them twice in a week, I might pursue more. Tell me though? They had the pure untampered Qur'an as well?
By the way, do you have any more details on the jpg you posted? It looks like it's the inside of a freight plane?
