Many Christians really do need a fresh reading of the Gospels and the book of Acts. There is way too much theology that has been taught that does not line up with the narrative given to us from Matthew through Acts.
For instance, the early church was predominately Jewish believers. The national Jews who rejected the gospel were the ones who were primarily responsible for the persecution of the first Christians. They persecuted their kinsmen who were followers of Jesus because they viewed them as a religious sect only and saw them as a threat to their religious and national status.
The message of the Gospel was sent to the House of Israel first, and in due time the Gospel began to spread all over the world to Gentiles everywhere.
The concept that the church of the Lord Jesus Christ is a Gentile entity is contrary to the narrative. The church is the Israel of God under the New Covenant for the New Covenant was made with the House of Israel and the House of Judah. This New Covenant with Israel was established by the blood of Jesus, the Messiah, and it is through this covenant that the Gentiles have been grafted into the House of Israel with the Jews who believe in the Messiah.
The church is born again Israel which has it’s beginning with 120 Jewish followers of Jesus that continued to grow enduring persecution from their kinsmen in the flesh.
When Jesus died and rose again, God’s covenant with israel in the flesh came to an end, and the New Covenant that God had promised to Israel was inaugurated.
When the Jewish temple was destroyed in 70 AD, the religious service which pertained to the Old Covenant, though it had already been made ineffective, became completely inoperative.
Under the Old Covenant, there were Gentiles were joined Israel and became a part of Israel. This was a type of the Church which began with Jewish followers of Jesus with Gentiles being added to them. God’s covenant people are no longer defined by a physical nation with natural boundaries. God’s people are in every nation.
So don’t blame the Gentiles for this. It was the Jewish followers of Jesus who obeyed Jesus’ command and began making disciples of people from other nations.
The followers of Jesus, consisting of Jews and Gentiles in one body are born again Israel, for they are partakes of the New Covenant which God gave to ISRAEL!
“The days are coming, declares the Lord, when I will make a new covenant WITH THE PEOPLE OF ISRAEL and WITH THE PEOPLE OF JUDAH. It will not be like THE COVENANT I made with THEIR ANCESTORS when I took them by the hand to lead them out of Egypt, because they did not remain faithful to my covenant, and I turned away from them, declares the Lord. THIS IS THE COVENANT I will establish WITH THE PEOPLE OF ISRAEL after that time, declares the Lord. I will put my laws in their minds and write them on their hearts. I will be their God, and they will be my people. No longer will they teach their neighbor, or say to one another, ‘Know the Lord,’ because they will all know me, from the least of them to the greatest. For I will forgive their wickedness and will remember their sins no more.” By calling this covenant “new,” he has made the first one obsolete; and what is obsolete and outdated will soon disappear. (Hebrews 8:8-13)
