Not nearly to the extent as was the case in OT times. How many Gentiles were saved in OT times? A very low percentage of them, right? In Noah's day only 8 people were saved. In the rest of OT times it was mostly only Israelites who were saved.
That's why Paul said this about the Gentiles:
Eph 2:11 Therefore, remember that formerly you who are Gentiles by birth and called “uncircumcised” by those who call themselves “the circumcision” (which is done in the body by human hands)— 12 remember that at that time you were separate from Christ, excluded from citizenship in Israel and foreigners to the covenants of the promise, without hope and without God in the world. 13 But now in Christ Jesus you who once were far away have been brought near by the blood of Christ.
How many have been saved in NT times? Many millions at least, right? Much more than in OT times, right? So, why are you acting as if there hasn't been much difference between how things were in OT times compared to NT times when that is clearly not the case?
