Revelation provides us with high-def footage of the climactic conclusion of world history, it ties together and consummates all of God’s redemptive purposes in this world, and it delivers us to the doorstep of a glorious eternity. And a conscious awareness of this truth will begin to change our entire perspective of this world. If we listen carefully, this hearing will become heeding.Read the whole thing.
It appears that one of God’s main purposes in the book of Revelation is simply this–He wants to change us. He wants to change how we live, what we live for, how we treat our spouse and children and friends, how we order our goals, what we prioritize, the zeal with which we kill personal sin, the purity of the local church, our compassion towards the hurting, our counsel for fellow sinners, our love for the lost, our earnestness to obey, our diligence to pray, our disgust of our personal worldliness, our heartfelt earnest longing for the return of Christ. God wants us to be holy like His Son.
If you're looking for a competant, worshipful, non-technical commentary on the book, my first choice would be Dennis Johnson's Triumph of the Lamb: A Commentary on Revelation.
