The Apostle Paul had much to say to the gentiles about their relationship with the Jewish people, even warning them to not boast or become arrogant against them. Paul made these critical points in his message to the church at Rome, specifically Chapters nine through eleven. I have paraphrased and emphasized these below, and I believe scripture speaks plainly for itself.
I never had any interest in ministry work, mainly because I was more interested in pursuing my own career goals as a Civil Engineer. However, the Lord had other plans for my life. If I have learned anything in my relatively short walk with the Lord, it is that His ways are not only different than ours but are most often opposite ours. It is written, “There is a way that seems right to a man, But its end is the way of death” (Proverbs 14:12). Yeshua said it like this, “He who does not take his cross and follow after Me is not worthy of Me” (Matthew 10:38); “For what profit is it to a man if he gains the whole world, and loses his own soul?” (Matthew 16:26).
“For I could wish that I myself were accursed from Christ [Yeshua] for my brethren, my countrymen according to the flesh, who are Israelites, to whom pertain the adoption, the glory, the covenants, the giving of the law, the service of God, and the promises; of whom are the fathers and from whom, according to the flesh, Christ came, who is over all, the eternally blessed God. Amen” (Romans 9:3-5).
