What does it mean to "Enter into the Kingdom of Yahweh"?
What and where is Yahweh's Kingdom?
We don't want to concentrate too much on religion. Kingdoms are governments with a ruler called a king - NOT religions (see Church or Kingdom?). It is the kingdom - a Government - a Nation.
Isa.9.6-7
For unto us a child is born, unto us a son is given: and the government shall be upon his shoulder: and his name shall be called Wonderful, Counsellor, The mighty Yahweh, The everlasting Father, The Prince of Peace. Of the increase of his government and peace there shall be no end, upon the throne of David, and upon his kingdom, to order it, and to establish it with judgment and with justice from henceforth even for ever. The zeal of Yahweh of hosts will perform this.
This prophecy speaks ONLY of government and Kingdom. Nothing is mentioned about church (nor salvation, nor redemption).
The purpose of the birth of the Son was to rule as king in Yahweh's Kingdom.
John.18.37
Pilate therefore said unto him, Art thou a king then? Yahushua answered, Thou sayest that I am a king. To this end was I born, and for this cause came I into the world...
Republics are generally more democratic than monarchies. Monarchy and Kingdom are synonymous and have a King (or queen) as ruler. The king's rule is autocratic. There aren't public elections to decide issues. The king decrees the law.
The "citizens" of a kingdom are generally referred to as "subjects" or "citizens". For purposes of this discussion, we will refer to governments synonymously with "cities", "states", "countries", "nations" and "kingdoms".
Kings are usually hereditary. If one NOT in the hereditary line assumes control, it is done through war or a coup.
This is why the Messiah had to be a descendant and in the direct line of King David. He was a hereditary heir to the throne. This lineage also shows that the Messiah was not an usurper, but had a legitimate claim to the throne. Satan was the usurper.
Here's the conclusion of the whole matter:
You are either a citizen of Yahweh's Kingdom or a citizen of Satan's kingdom (Babylon). Your Father and King is either Yahweh or it is the king of Babylon. If you are a citizen of Babylon, you are admonished to come out of her and to enter the Kingdom of Yahweh.
There is no neutral country between these two warring nations. No fence-sitting. It is either one or the other.
Remember, this is NOT a discussion of CHURCH. We are discussing GOVERNMENT. Not church membership, but citizenship.
Rev.14.8
And there followed another angel, saying, Babylon is fallen, is fallen, that great city, because she made all nations drink of the wine of the wrath of her fornication.
Rev.18.10
Standing afar off for the fear of her torment, saying, Alas, alas that great city Babylon, that mighty city!
Babylon is a city - cities are government. In Bible symbols, two specific cities are represented as women. Babylon is called a "city". Babylon is also a kingdom government (see Gen.10.10, Isa.14.4, Jer.50.43, Dan.2.37)
Rev.18.4
And I heard another voice from heaven, saying, Come out of her [Babylon], my people, that ye be not partakers of her sins, and that ye receive not of her plagues.
We need to withdraw from (come out of, exit or exodus from) that government and enter Yahweh's government.
One becomes a citizen of the United States by birth. One becomes a citizen of Canada by birth. One becomes a citizen of Mexico by birth. Every government on earth recognizes citizenship by birth. Likewise, one becomes a citizen of the Kingdom of Yahweh by birth.
Yahushua clearly taught Nicodemus this truth:
John.3.3,5
Yahushua answered and said unto him, Verily, verily, I say unto thee, Except a man be born again, he cannot see the kingdom of Yahweh ... Verily, verily, I say unto thee, Except a man be born of water and of the Spirit, he cannot enter into the kingdom of Yahweh.
