#1. Who is this spoken to: He was in the world, and the world was made through Him, and the world did not know Him.
He came to His, and His own did not receive Him. But as many as received Him, to them He gave the right to become children of God, to those who believe in His name: who were born, not of blood, nor of the will of the flesh, nor of the will of man, but of God.
#2. Who is this spoken to: Jesus answered and said to them, “This is the work of God, that you believe in Him whom He sent.
#3. Who is this written to: Jesus answered, “Most assuredly, I say to you, unless one is born of water and the Spirit, he cannot enter the kingdom of God. That which is born of the flesh is flesh, and that which is born of the Spirit is spirit. 7Do not marvel that I said to you, ‘You must be born again.’ The wind blows where it wishes, and you hear the sound of it, but cannot tell where it comes from and where it goes. So is everyone who is born of the Spirit.
#4. Who is this spoken to: Jesus said: For God so loved the world that He gave His only begotten Son, that whoever believes in Him should not perish but have everlasting life. For God did not send His Son into the world to condemn the world, but that the world through Him might be saved.
#5. Who is this spoken to: Most assuredly, I say to you, he who hears My word and believes in Him who sent Me has everlasting life, and shall not come into judgment, but has passed from death into life. Most assuredly, I say to you, the hour is coming, and now is, when the dead will hear the voice of the Son of God; and those who hear will live.
#6. Who is this spoken to: And Jesus said to them, “I am the bread of life. He who comes to Me shall never hunger, and he who believes in Me shall never thirst.
One through six was spoken to Israel because Christians were not yet there. Here maybe this will help...
We must understand these administrations have different time periods in the Bible and each have their own beginning and their own ending—with the exception of the last one.
The first is called the Paradise administration. It was the time of innocence, the time before the fall that ends with Adam and Eve being expelled from the garden of the original paradise.
The second is the Patriarchal administration. It was the time after the fall from the Garden of Eden, but before the Law was given. This second administration ended with the coming of the Law to Moses.
The third is the Legal administration. It's suited only to Israel under the Law, and is sometimes called the Mosaic Law that terminated when Jesus Christ died.
The fourth is the Christ administration that overlapped and functioned within the Law administration. Both the Law and the Christ administration officially ended with the coming of Pentecost.
The fifth started on the day of Pentecost as recorded in the second chapter of the book of Acts. This is the present administration of Grace that is for the Church of God. It's the time period you and I now belong to because it's the Grace administration, without any distinction made between the Jew and the Gentile, which will end with the appearing of Jesus Christ.
The sixth begins with the appearing of Jesus Christ, and the gathering together of the saints. Believe it or not, this administration ends with Satan destroyed, and the great white throne judgment.
The seventh is the Glory or Paradise administration, which will not have an ending.
Administrations must be adapted to the time periods in which they are carried out. The administration with Adam before the fall was different from the one with his immediate family after the fall. The administration with Israel “under the law” was carried out on different principles from the present administration of Grace. This present administration is different from the one that will characterize the return of Christ. The administration of Judgment will be different from the one that will belong to the administration of Glory, when all things shall be gathered together in one under the headship of Christ.
