Hi Stef,
 

Allow me to explain first, the mysterious words of scriptures, into simple words, which are explained by the Truths of Life, God´s True Will and Works.
 

Is the marriage supper of the Lamb only for the saints who have been raptured before the Tribulation?
 

These Words, which are used in your question are mixed up, and doesn’t express the Truths of Life. Let’s handle first, what shall happen very soon on Earth and define all Words and place them in the exact order below. So, all the words of the Prophets starts to make sense, for Everyone who listens.
 

Earth is going to be restored by two celestial systems, from an unbalanced and disharmonious Earth (caused by Man), into a balanced and harmonious New Earth by an Apocalypse. This Apocalypse is described as the Day of the Lord.
 

The time of restoration of Earth into a new Earth is called Great Tribulations. Tribulations is the time, where people have to endure havoc and chaos on Earth to prove, if they have evolved in a human life and are Worthy Saints. What is called the Judgement of Man on Earth, during the Tribulations. If they live on Earth, as harmonious Man, as Saints by God’s True Ways or Not.
 

God True Ways is To be Loving, Equal, Caring, Sharing, Kind, Good and Peaceful, all the time, for Everyone and Nature. Only the Saints shall be protected by their lifted human Souls during these ordeals of the Great tribulations on Earth. And only the Saints shall survive and endure as Sole-survivors and inherit New Earth.

All others, as the Wicked and people with still an ego perspective in their thoughts, shall all die during the Great Tribulations, called the Rapture. Where billions of died people, shall ascend as human Souls into the In-between life (=afterlife). To learn there, to purify and to evolve their human Souls in their real, unknown by Man, In-between life. To experience here a “second death”.

For the Saints, as New Harmonious Man to start over again in a New harmonious civilization, in a New main cycle of life on New Earth, in the beginning of the Age of Aquarius. Called the Age of Harmony.
 

The Messiah is going to restore by Words and Guidance the disharmonious and unbalanced thoughts and ways of Man into harmonious and balanced thoughts and ways of God, as the third system. So, Man who study, Seals and Lives by the Words of the Messiah, by choice and free will are Ready to live in a harmonious new civilization on New Earth, where Sin and almost all of Ego does Not exist anymore. What is described as the “marriage” between Man and the Messiah, to become the Chosen Ones, the Overcomers. Because these Saints chose by free will, to listen, Seal and Live the Words of Christ, the Messiah. It is called a supper, because the Words of the Messiah is food for the human Souls, who are ready to listen to his Words, how to become a Worthy Saint. They have to consume the Words as bread, and to LIVE the Words.
 

These two celestial systems, which one of them we are experiencing already on Earth, is INCREASING the activities expressed as Signs by volcano’s, fireballs, earthquakes, floods, storms, sinkholes, the expanding of Earth, increasing pressure and temperature in magma and rapid climate changes. What is the real reason for the so-called, climate change, it’s happening, unfolding and real.
 

The Marriage supper of the Lamb, is to learn, Seal and Live the Words of the Messiah, To learn how to become a harmonious, loving human being, as a Saint. Only they shall survive Great Tribulations and live further on Earth. Where a new harmonious civilization is created, living without Sin. To restore Harmony and Balance on Earth, for Everyone and Nature again. Literally to start over again.
 

All others, who did Not became a Perfect Saint, shall die in the Rapture of Great Tribulations, they are Not Ready as Man, to enter the Age of Harmony, biblical called, “Age of Kingdom” in our New Earth. And they are Not Ready as human Souls to return almost instantly unto Heaven. Because, they did Not became a purified, loving, good and kind human Soul, as Man. They still, have to purify their human Souls in their Real In-between life, in their real Repentance Phase by Works (in afterlife). It is what it is, nothing more and nothing less.
 

The Revelations of an In-between life, I have many times explained, over and over again. Learn and comprehend you have an eternal life as Soul. Once you understand the complete cycle of life, of a Godly Soul from Heaven into a human Soul in the In-between dimension, into Man of our apparently material dimension and back into a human Soul, into your Godly Soul and to return to Heaven, you shall know you can never die. And there is Nothing on Earth or beyond, that needs to be feared. Fear is only caused by your own thoughts, over and over again. A new Time, is going to be created on Earth, it is just a choice, to belong in New Earth or Not.

To pass the narrow gate into the Age of Harmony in new Earth or into Heaven, you need to purify your human Soul, as your thoughts, memory and personality. To support and guide Man you can find simple words explaining this knowledge and wisdom in this website.
 

The information to purify your human Soul, how to become a Saint and lift your human Soul has already been revealed. Just, simple Words to live, or not. Have a look; Book of Life, Age of Harmony 2025 - 4185, where everything is step by step explained.
 

Choices are causes, and causes have consequences in this human life and even in your real In-between life. Learn to choose right choices, and evolve yourself and help others too.
 

Life is all about thoughts and choices.

Choose well.
