That depends. Are you ONLY working from the Law and Prophets? Or are you also working from the New Testament too?
If you’re only working from the L & P your perspective is going to be skewed. Though, He made it known even there that His plan included all who would believe.
“And he said, It is a light thing that thou shouldest be my servant to raise up the tribes of Jacob, and to restore the preserved of Israel: I will also give thee for a light to the Gentiles, that thou mayest be my salvation unto the end of the earth.”
Isaiah 49:6 KJV
“The Lord GOD which gathereth the outcasts of Israel saith, Yet will I gather others to him, beside those that are gathered unto him.”
Isaiah 56:8 KJV
“And the Gentiles shall come to thy light, and kings to the brightness of thy rising.”
Isaiah 60:3 KJV
“I saw in the night visions, and, behold, one like the Son of man came with the clouds of heaven, and came to the Ancient of days, and they brought him near before him. And there was given him dominion, and glory, and a kingdom, that all people, nations, and languages, should serve him: his dominion is an everlasting dominion, which shall not pass away, and his kingdom that which shall not be destroyed.”
Daniel 7:13-14 KJV
“In that day will I raise up the tabernacle of David that is fallen, and close up the breaches thereof; and I will raise up his ruins, and I will build it as in the days of old: that they may possess the remnant of Edom, and of all the heathen, which are called by my name, saith the LORD that doeth this.”
Amos 9:11-12 KJV
It is clear from the Prophets that they saw His plan, in pieces for sure, enough to know that He would call the gentiles to Himself.
If you’re including the New Testament then it is even clearer.
The real question is - are you being genuine or just trying to stir the pot?
