The prophet Isaiah connects the messiah to a time where all people on earth know about God:

“(…) the earth will be filled with the knowledge of the Lord as the waters cover the sea.”

Isaiah 11:9

Further we read the following:

“The Lord will be king over the whole earth. On that day there will be one Lord, and his name the only name.”

Zechariah 14:9

When we look at statistics, it becomes clear that Christianity is indeed the largest religion:

Despite this achievement of becoming the largest religion globally, Christianity is obviously not the only religion. This however was prophesied by Isaiah and Zechariah. So how can Christians claim that Jesus is the Messiah?

Jesus came to earth to begin making the true spirit of God known

Let’s face it, without Jesus, the God described in the books of Moses would remain largely unknown to the world. As statistics show, Judaism accounts for only around 15 million people (roughly 0.2% of the global population) in 2020. 

Although the universal knowledge of God is not yet implemented, Jesus initiated the movement to make the God of Moses known to billions. Today, 2’000 years after Jesus, from the roughly 8 billion inhabitants on earth globally, around 30% identify as Christians — meaning they are somewhat familiar with the Bible (Old and New Testament) and the Ten Commandments.

Shortly before his death, Jesus prayed to God, affirming that he had fulfilled his mission by revealing the true nature of God and commissioning his disciples to continue spreading God’s word. The enduring impact of their efforts is evident in the global presence of Christianity more than 2,000 years later:

“After Jesus said this, he looked toward heaven and prayed:“Father, the hour has come. Glorify your Son, that your Son may glorify you. For you granted him authority over all people that he might give eternal life to all those you have given him. Now this is eternal life: that they know you, the only true God, and Jesus Christ, whom you have sent. I have brought you glory on earth by finishing the work you gave me to do. (…)

I have revealed you to those whom you gave me out of the world. (…) Now they know that everything you have given me comes from you. For I gave them the words you gave me and they accepted them. They knew with certainty that I came from you, and they believed that you sent me. (…) they are still in the world, and I am coming to you. Holy Father, protect them by the power of your name, the name you gave me, so that they may be one as we are one. (…)

(…) I have given them your word and the world has hated them, for they are not of the world any more than I am of the world. (…) As you sent me into the world, I have sent them into the world. (…)

Righteous Father, though the world does not know you, I know you, and they know that you have sent me. I have made you known to them, and will continue to make you known in order that the love you have for me may be in them and that I myself may be in them.”

John 17:1-26

The Ultimate Fulfillment: God Dwelling with Humanity and Universal Knowledge of the Lord

A closer reading of the Bible reveals that its authors, inspired by God, understood that the fulfillment of universal knowledge of God would unfold over time. The book of Revelation, with its prophecies of hope for the future, indicates that this era is still to come:

“All nations will come and worship before you, for your righteous acts have been revealed.”

Revelation 15:4

The Bible goes on to describe a future when God will personally live among people, marking an era in which everyone will know Him:

“Then I saw “a new heaven and a new earth,” for the first heaven and the first earth had passed away, and there was no longer any sea. I saw the Holy City, the new Jerusalem, coming down out of heaven from God, prepared as a bride beautifully dressed for her husband. And I heard a loud voice from the throne saying, “Look! God’s dwelling place is now among the people, and he will dwell with them. They will be his people, and God himself will be with them and be their God.”

Revelation 21:1-3

To summarize, to me this shows that Jesus successfully completed his mission on earth by selecting disciples who were ready to carry the fire of love he ignited within them and the embedded word of God out into the world. Despite facing intense persecution initially, Christianity has become the world’s largest religion. The Bible teaches that the complete fulfillment of universal knowledge of God is still in the future, giving Christian believers hope as they look forward to its realization.

Ultimately, the prophecies of Isaiah and Zechariah point to a process that began with Jesus and continues through his followers, with the final fulfillment anticipated in the future reign of God.

Universal knowledge of God in the visions of Maria Valtorta

The visions of Maria Valtorta show multiple passages related to this topic. Here two examples.

In the first one, Jesus is called by a Roman soldier to heal his wounded Roman colleague and to the disguise of other hebrews he follows the Roman soldier and tells him that God is here for everyone, Jews and Gentiles, and that he came to make the true God known: 

“Jesus follows the non-commissioned officer, who devours the way with his brawny legs free from hampering clothes. But even striding thus ahead of everybody, he manages to speak some words to Him Who is the first to follow him, that is to Jesus, and he says: « Some time ago I was with Alexander. He… used to speak of You. Chance has put You close to me just now.»

« Chance? Why not say God? The true God?»

The soldier is silent for a moment, then in a low voice so that Jesus only can hear he says: « The true God would be the Hebrew one… But He does not make Himself loved, if He is like the Hebrews. They do not take pity even on a wounded man… »

« The true God is the God of the Hebrews, as well as of the Romans, the Greeks, the Arabs, the Parthians, the Scythians, the Iberians, the Gauls, the Celts, the Lybians, the Hyperboreans. There is but one God! But many do not know Him, others have a wrong knowledge of Him. If they knew Him well, they would all be like brothers to one another, and there would be no abuse of power, no hatred, no slander, no revenge, no lust, no thefts, no homicides, no adulteries and no falsehood. I know the true God and I have come to make Him known.”

Maria Valtorta, The Poem of the ManGod, chapter 512. The Undecided Young Man. Miracles and Admonitions at Beth-Horon.

In the second one, Jesus has a conversation with Greek gentiles about God and him being universally known in the future:

“«They say that the Messiah will be the Redeemer, and that You are such… Is it true?»

«It is true. It is I Who am speaking to you.»

«So, You will have to die? Why, Master? The world is in such great need of Light, and You want to leave it?»

«You, a Greek, are asking Me this? You, who are dominated by Socrates’ words?»

«Master, Socrates was a just man. You are holy. Consider how much the Earth needs holiness.»

«It will be raised to the ten thousandth power for each sorrow, each wound and drop of My Blood.»

«By Jove! Never was there a Stoic greater than You, as You do not just preach the contempt of life, but You are preparing Yourself to throw it away.»

«I do not despise life. I love it as the most useful thing to buy the salvation of the world.»

«But You are too young, Master, to die!»

«Your philosopher says that what is holy is dear to the gods, and you said that I am holy. If I am holy I must long to go back to the Holiness from Which I came. So never young enough not to have such longing. Socrates also says that he who is holy loves to do things pleasant to the gods. What is more pleasant than restoring to the embrace of the Father the children whom sin had banished, and giving man peace with God, the source of all wealth?»

«You say that You do not know Socrates’ words. How come then, that You know the ones You have spoken?»

«I know everything. The thoughts of men, when they are good thoughts, are nothing but the reflection of a thought of Mine. When a thought is not good, it is not Mine, but I have read it in the succession of times and I knew, I know and will know, when it was, is and will be spoken. I know.»

«Lord, come to Rome, the light of the world. You are surrounded by hatred here. You will be surrounded by veneration there.»

«It would surround man, not the Master of the supernatural. I have come for the supernatural. I must bring it to the children of the People of God, although they are the most stubborn against the Word.»

«So Rome and Athens will not have You?»

«They will have Me. Be not afraid. They will have Me. Those who want Me will have Me.»

«But if they are going to kill You…»

«The spirit is immortal. The spirit of every man is immortal. Will Mine not be so, the Spirit of the Son of God? I will come with My active Spirit… I will come… I can see numberless crowds and the Houses erected in My Name… I am everywhere… I will speak in cathedrals and in hearts… My evangelization will know no rest… The Gospel will travel all over the Earth… all good people towards Me… and there… I go by at the head of My multitude of saints and I lead it to Heaven. Come to the Truth…»”
