‘The Revelation of Jesus Christ’, is particularly the revelation about how he will be with, protect, and strengthen his church through the last age and bring it to final triumph. ‘Which God gave unto him [unto Christ] to show unto his servants things which must shortly come to pass.
Many good believers think that the book of Revelation is mostly about things that happen at the end of time. But that is not what it says here at the very beginning of the book. It says it is a revelation, an unveiling, a revealing of things which will shortly begin to happen. This is a book about things that would happen from the time John was shown these things, right down the centuries – 2,000 years already – and until the Lord shall come again.
