23 "administrations"? Really?What is written directly to the Jews, belongs to and is for the Jews. What is written directly to the Gentiles, belongs to and is for the Gentiles. What is written directly to the Church of God, belongs to and is for the Church of God. What does God mean when He tells us that the visions shown to Isaiah was concerning Judah and Jerusalem? It was not addressed to us or written concerning us, but it was addressed to and concerning Judah and Jerusalem. It would be dishonest for the Church of God to interpret to the Church of God what God said concerns Israel.
The present administration of God is in the time period of the New Testament known as Grace. It deals with the new covenant, and it belongs to the time that is called the administration of the mystery. It's a period in time that was not made known to any one prior to this administration because God kept it a secret since the world began. From this our Grace administration, we learn God’s secret purpose that He had placed in Himself, according to the administration of Grace, which was first revealed to the apostle Paul.
There are no more Jews. We are now within the time period of Christians. 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.
