No I'm not a Gentile, but you asking the wrong questions. The question is How can one who is not of the lineage of Israel, become partakers of the covenant of God? Lets take a look in (Ephesians 2:11-22) let’s look at the 11th through 13th verses. "Wherefore remember, that ye being in the time past Gentiles in the flesh, who are called uncircumcision by that which is called the circumcision in the flesh made by hands; (12th vs.) That at that time ye were without Christ, being aliens from the commonwealth of Israel, and strangers from the covenant of promise, having no hope, and without God in the world: (13th vs.) But now in Christ Jesus ye who sometimes were far off are made nigh by the blood of Christ." 9 Now therefore ye are no more strangers and foreigners, but fellowcitizens with the saints, and of the household of God; 20 and are built upon the foundation of the apostles and prophets, Jesus Christ himself being the chief corner stone;
"Here is the patience of the saints; here are they that keep the commandments of God and the faith of Jesus" (Revelation 14:12).
Paul said in Romans 2:7 To them who by patient continuance in well doing seek for glory and honour and immortality, eternal life: 8 But unto them that are contentious, and do not obey the truth, but obey unrighteousness, indignation and wrath, 9 Tribulation and anguish, upon every soul of man that doeth evil, of the Jew first, and also of the Gentile; 10 But glory, honour, and peace, to every man that worketh good, to the Jew first, and also to the Gentile: 11 For there is no respect of persons with God. 12 For as many as have sinned without law shall also perish without law: and as many as have sinned in the law shall be judged by the law; 13 (For not the hearers of the law are just before God, but the doers of the law shall be justified.
There more, the point is that there is an order in how God set up his priesthood, Jesus is the High priest, but Israel is still the priest of God to this day. Rejecting God's counsel will get you eternal life in the burning flames (lake of fire) with the scribes and Pharisees. "For I say unto you, that except your righteousness shall exceed the righteousness of the scribes and Pharisees, Ye shall in no case enter into the kingdom of heaven." (Matthew 5: 20).
