John Stott remarks:
‘Just as the letters of Paul convey the word of God to us as well as them, to London, New York and Cairo as well as to Corinth and Thessalonica, so Christ's letters through John to the first century Christian communities of Asia have a permanent value and a universal message.
The devil's tactics do not change. As we look around the world today, the same pressures are harassing different churches. In some areas of the world, open hostility to the gospel. In others, intellectual combat with an insidious ideology or a materialistic philosophy. Elsewhere the struggle is in the moral field ... the book of Revelation is a call to us to endure tribulation, to hold fast to the truth, to resist the blandishments of the devil and obey the commandments of God’.
