Are you saying that the tribulation is used as some purification process for the Church?
Gods Word says it. It is for everyone, for the purposes of God. God is Just. God wishes all to come to repentance. God does not want to lose anyone.
God can not change. He is the same yesterday, today and tomorrow.
At the most basic level.
Revelation 22:10 And he saith unto me, Seal not the sayings of the prophecy of this book: for the time is at hand.
Revelation 22:11 He that is unjust, let him be unjust still: and he which is filthy, let him be filthy still: and he that is righteous, let him be righteous still: and he that is holy, let him be holy still. (GOOD AND EVIL)
Revelation 22:12 And, behold, I come quickly and my reward is with me, to give every man according as his work shall be. (NOT JUST SOME)
Revelation 22:13 I am Alpha and Omega, the beginning and the end, the first and the last.
Revelation 22:14 Blessed are they that do his commandments, that they may have right to the tree of life, and may enter in through the gates into the city.
Revelation 22:15 For without are dogs, and sorcerers, and whoremongers, and murderers, and idolaters, and whosoever loveth and maketh a lie. (AND WHAT LIES IS GOD REALLY CONCERNED WITH? HIS WORD. AND HOW CAN WE BE SURE?)
Revelation 22:16 I Jesus have sent mine angel to testify unto you these things in the churches. I am the root and the offspring of David, and the bright and morning star.
Revelation 22:17 And the Spirit and the bride say, Come. And let him that heareth say, Come. And let him that is athirst come. And whosoever will, let him take the water of life freely.
Revelation 22:18 For I testify unto every man that heareth the words of the prophecy of this book, If any man shall add unto these things, God shall add unto him the plagues that are written in this book: (HERE IS PROOF)
Revelation 22:19 And if any man shall take away from the words of the book of this prophecy, God shall take away his part out of the book of life, and out of the holy city, and from the things which are written in this book. (AND OUR SECOND WITNESS)
Revelation 22:20 He which testifieth these things saith, Surely I come quickly. Amen. Even so, come, Lord Jesus.
Revelation 22:21 The grace of our Lord Jesus Christ be with you all. Amen.
