1For this cause I, Paul, am the prisoner of Christ Jesus on behalf of you Gentiles, 2if it is so that you have heard of the administration of that grace of God which was given me toward you, 3how that by revelation the mystery was made known to me, as I wrote before in few words, 4by which, when you read, you can perceive my understanding in the mystery of Christ, 5which in other generations was not made known to the children of men, as it has now been revealed to his holy apostles and prophets in the Spirit, 6that the Gentiles are fellow heirs and fellow members of the body, and fellow partakers of his promise in Christ Jesus through the Good News, 7of which I was made a servant according to the gift of that grace of God which was given me according to the working of his power. 8To me, the very least of all saints, was this grace given, to preach to the Gentiles the unsearchable riches of Christ, 9and to make all men see what is the administration of the mystery which for ages has been hidden in God, who created all things through Jesus Christ, 10to the intent that now through the assembly the manifold wisdom of God might be made known to the principalities and the powers in the heavenly places, 11according to the eternal purpose which he accomplished in Christ Jesus our Lord. 12In him we have boldness and access in confidence through our faith in him. 13Therefore I ask that you may not lose heart at my troubles for you, which are your glory.
14For this cause, I bow my knees to the Father of our Lord Jesus Christ, 15from whom every family in heaven and on earth is named, 16that he would grant you, according to the riches of his glory, that you may be strengthened with power through his Spirit in the inner person, 17that Christ may dwell in your hearts through faith, to the end that you, being rooted and grounded in love, 18may be strengthened to comprehend with all the saints what is the width and length and height and depth, 19and to know Christ’s love which surpasses knowledge, that you may be filled with all the fullness of God.
20Now to him who is able to do exceedingly abundantly above all that we ask or think, according to the power that works in us, 21to him be the glory in the assembly and in Christ Jesus to all generations, forever and ever. Amen.
Revelation (Gk. ἀποκάλυψις, apokalypsis) Strong’s 602
This word is used eighteen times in the NT. It means to “uncover, reveal.” It can be used in the sense of revealing truth, or revealing a thing or person, such as the glory of Christ, the Lord Himself or the children of God. Revelation seems to refer to the uncovering of some aspect of reality previously hidden, either conceptually or physically. This can include the arrival of a person, whose very presence constitutes a revelation of some important aspects of reality, especially if that person is divine.
This word used in Rev 1:1 is tantamount to a title. Beyond this, the word seems to be used with a double meaning in this verse. The revelation of Jesus Christ definitely refers to an event, in the context of the book, and that event is the second coming of Christ. There is also much that is “revealed” to John in the discussion surrounding that event, and what is written is likewise a revelation to his readers. The book of Revelation, then, is both an announcement of the revelation (coming) of Jesus Christ, and a window on the nature of certain very dramatic spiritual and heavenly realities that will find profound physical expression and that are here revealed ahead of time.
