Kindness is about mercy and compassion.
I will have mercy on whom I will have mercy, and I will have compassion on whom I will have compassion. (Romans 9:15) "KJV"
Religion is a light for the unbeliever just as the knowledge of God in non-religious places is a light for the religious. Binary black-hole merger in gravitational wave astronomy is a light for the religious, light cone in physics is a light for the religious, and the knowledge of space-time continuum is a light for the religious.
On the other hand, Christ is a light for the Atheists, Mandala is a light for the unbeliever, and the holy of Holies is a light for the unbeliever.
Therefore, the religious with the unbeliever is an object with its mirror image. When the object is Theist, the image is the Atheist; when the object is the Atheist, the image is the Theist. Since the image is the same as the object, Theists and Atheists are the same people of God.
I will call them my people, which were not my people; and her beloved, which was not beloved. (Romans 9:25) "KJV"
My people: the Jews.
Not my people: the Gentiles.
The Theists are the Jews and the Atheists are the Gentiles, when the wisdom of God is coming from the Jews to the Gentiles. And the Atheists are the Jews and the Theists are the Gentiles when the knowledge of God is coming from the Atheists to the Theists.
The flow of the knowledge of God from Atheists to Theists is the descent of the holy city.
That great city, the holy Jerusalem, descending out of heaven from God (Revelation 21:10) "KJV"
Great city: the cosmos (Christ).
The Cosmos = the Holy Jerusalem
Since the cosmos is Christ, the knowledge of the cosmos, coming from the Atheists to the Theists, is Christ descending from the Gentiles to the Jews. Up is where the knowledge is coming from, and Down is where the knowledge is going.
John of Patmos was a religious man (a Jew) which means that he received the knowledge of the cosmos from the Atheists. Small wonder he said the Great City was descending from heaven (Up) to him (Down).
The implication is that God, who was dwelling among the Atheists, is returning to the Theists. The return means that God is coming to reconcile the Theists and the Atheists into one united people of God.
In the place where it was said unto them, Ye are not my people; there shall they be called the children of the living God. (Romans 9:26) "KJV"
