We ought to read the scriptures through the lens of the Holy Spirit and rightly divide the word of truth.
Jesus came to the Jews first, but Israel is God's showcase of glory to the world and the two houses will be joined back together.
God is concerned for all men, and all are called to God eventually. You have many things right, but you must include all of what scriptures teach and you have not done so.
Paul's ministry was to the Gentiles and yes, the house of Israel were gentiles in the way that they lived their lives and God considered them as such in the way they perceived their selves. However, God is concerned for those other than the House of Israel and God called many not of Israel to himself as well.
Now, consider this scripture in its proper context and believe it and teach it:
1Ti 2:1 I exhort therefore, that, first of all, supplications, prayers, intercessions, and giving of thanks, be made for all men;
1Ti 2:2 For kings, and for all that are in authority; that we may lead a quiet and peaceable life in all godliness and honesty.
1Ti 2:3 For this is good and acceptable in the sight of God our Saviour;
1Ti 2:4 Who will have all men to be saved, and to come unto the knowledge of the truth.
All is referring not to a particular group but is all inclusive and this you must teach!
1Ti 4:9 This is a faithful saying and worthy of all acceptation.
1Ti 4:10 For therefore we both labour and suffer reproach, because we trust in the living God, who is the Saviour of all men, specially of those that believe.
1Ti 4:11 These things command and teach.
This is "all" men and God is the Savior of all men and it is not limited to a certain group bit is "all" inclusive we are commanded to embrace and teach that truth. If you do not do so, then you are rejecting Jesus and the gospel message.
Let us begin to see a change of mind in you that embraces Christ purpose for all people and rejoice in him who loves all of God's creation.
Joh 3:16 For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life.
Joh 3:17 For God sent not his Son into the world to condemn the world; but that the world through him might be saved.
Now, if Jesus does not accomplish his purpose, then he is not our Savior but an imposter.
God saves and God saves all in due course and no one is excluded.
Eph 1:10 That in the dispensation of the fulness of times he might gather together in one all things in Christ, both which are in heaven, and which are on earth; even in him:
Eph 1:11 In whom also we have obtained an inheritance, being predestinated according to the purpose of him who worketh all things after the counsel of his own will:
1Co 15:26 The last enemy that shall be destroyed is death.
1Co 15:27 For he hath put all things under his feet. But when he saith all things are put under him, it is manifest that he is excepted, which did put all things under him.
1Co 15:28 And when all things shall be subdued unto him, then shall the Son also himself be subject unto him that put all things under him, that God may be all in all.
Believe all these scriptures and teach them for if you do not you are in denial of Christ that is your Savior.
If you deny even one that God will not save, then you deny Christ who has saved you.
It is clear what God's will is:
Mat 6:9 After this manner therefore pray ye: Our Father which art in heaven, Hallowed be thy name.
Mat 6:10 Thy kingdom come. Thy will be done in earth, as it is in heaven.
Understand what God's will is for humanity and teach it!
Gen 1:27 So God created man in his own image, in the image of God created he him; male and female created he them.
Now, to be in God's true image is to be in Christ and God does what he says that he will do.
Thus, do what God commands you when he empowers your mind and heart to harmonize with God's will.
Mat 6:10 Thy kingdom come. Thy will be done in earth, as it is in heaven.
God bless you.
