In the books that fulfill the scripture the believers looked for a Saviour appearing when they shall appear with Him.
Those books tell of His Spirit within the believer, being
Complete in Him, of a heavenly calling and of eternal life.
There are warnings of traditions of men. Many traditions
are re-enacting instruction given to Israel that God set aside at Acts chapter 28. Search for the warnings of keeping traditions.
Abraham looked for a city that had foundation. He looked
for that city before instruction was given to the nations, before God
turned from instructions to Israel, to instructions to the nations
and the promise of a heavenly calling for believers, mentioning
high above all heavens. Israel is promised a new heaven and a new earth. That is a different promise than is found in the last books
Apostle Paul wrote to fulfill the scripture.
It is well to check to whom instructions are given. The book of
John is written to the world, the nations. It tells about Israel, but was written after Israel was set aside. There is a period of time not prophesied, between the setting aside of Israel and the millennium.
It was hid in God, the secret revealed in the books that complete the scripture. The apostle Paul was an apostle of Jesus Christ by the will of God. Read Ephesians 1:1, Colossians 1:1, Titus 1:1.
First Timothy 1:1 says,” Paul, an apostle of Jesus Christ by the commandment of God our Saviour, and Lord Jesus Christ, which is our hope."
