In Revelation 3, Jesus instructs John to write to the Church at Laodicea. He is concerned that this church is lukewarm, not hot nor cold. He began it this way:
"And unto the angel of the church of the Laodiceans write; These things saith the Amen, the faithful and true witness, the beginning of the creation of God;" (Revelation 3:14 KJV)
JESUS IS THE AMEN.
Pulpit Commentary says of The Amen, "The word "Amen" is here used as a proper name of our Lord; and this is the only instance of such an application. It signifies the "True One." It is a word much used in St. John's Gospel, where it appears repeated at the commencement of many discourses, "Verily, verily.""
Gills Commentary says of The Amen,
"Christ may be so called, because he is the God of truth, and truth itself; and it may be expressive of his faithfulness, both to God his Father, and to his people, in whom all the promises he either made, or received, are yea and amen; and also of the firmness, constancy, and immutability of Christ, in his nature, person, and offices, in his love, fulness of grace, power, blood, and righteousness..."
Jamieson-Fausset-Brown Bible Commentary says "His unchanging faithfulness as "the Amen" contrasts with Laodicea's wavering of purpose, "neither hot nor cold" (Revelation 3:16)."
In Isaiah 65:16 it is noted in the Hebrew He is the God of a-men (truth)
"So that he who blesses himself in the land shall bless himself by the God of truth," (God of Amen)
In the New Testament Paul explains, "For all the promises of God find their Yes in him. That is why it is through him that we utter our Amen to God for his glory." (2 Corinthians 1:20)
God is the God of truth, His Son is Truth, He is the Amen! John MacArthur explains both the Revelation 3:14 verse and the 2 Corinthians 1:20 verse:
"Scripture tells us in 2 Corinthians 1:20, a very important truth. It says, "For all the promises of God in Him are amen." All the promises of God in Him are amen. What does that mean? That means that all God's promises and all God's covenants are guaranteed and affirmed by the person and work of Jesus Christ. In the Old Testament God said I will forgive your sins. God could never do that if it were not for the person and work of Christ, right? Because forgiveness was purchased by His atoning death. All of the promises that God made to take men and show them mercy and loving kindness, grace and give them a Kingdom and a hope and an eternal life are bound up in Jesus Christ fulfilling His work. So that everything that God ever planned or purposed for man, everything that God ever promised for man finds its amen in Jesus Christ. God's promises are all certain in Him. They all become sure in Him. And so, Jesus Christ is God's amen, "
Happy New Year, Amen!
