The Apostle Paul makes some incredible statements about the ministry revealed to him after Israel as a nation were put aside at the end of the book of Acts. Here are just two of them;
Eph 3:1-3a For this cause, I, Paul, am the prisoner of Jesus Christ for you nations, if you have heard of the dispensation of the grace of God which is given to me toward you, that by revelation He made known to me the mystery....

And again;
Eph 3:7-9 Of this gospel I was made a minister, according to the gift of the grace of God given to me by the effectual working of His power. This grace is given to me (who am less than the least of all saints) to preach the gospel of the unsearchable riches of Christ among the nations, and to bring to light what is the fellowship of the mystery which from eternity has been hidden in God, who created all things by Jesus Christ;
 
See also 2 Tim.1:8-11 and Col.1:23-29 where Paul reaffirms that he alone received this present dispensation and in Col. says this ministry "fulfils the Word of God". That which had been hidden in God does not fulfill earlier truths so we should read "completes the Word of God" (cp Col.2:10). Only Paul can enlighten Christians  about the dispensation of the grace of God (Eph.3:9) and the myriad of denominational systems manifests the sad truth that very few fully understand it.

In this current dispensation Israel has no dispensational advantage, in fact from both Jew and Gentile God has created "one new man" (Eph.2:14-15), yet Christians want to be Israel, observe things given to Israel and worship and walk according to elements of dispensations other than their own; this in my opinion is ungodliness.

The non-application of the Bible study rules (Phils.1:9-10, 2 Tim.2:15) has resulted in confusion and ignorance of the present dispensation and the growing fascination for the things of Israel rather than the things of the Church which is His Body.
