BOOK OF REVELATION:
I am reading "China and End-Time Prophecy", and have a great tip about Revelation: The late Tony Ling from Ministries Without Borders had his two books "The Lion and The Lamb" Vol 1 & 2 published and also for free not long ago.

His church in UK published many things not long ago. I don't know if many files, audio, text can be shared here somehow, he gave them for the glory of God's Kingdom. That is what it was all for! :-)
