Elements of Replacement Theology continue to resonate in many people's thinking around here. What Jesus told Israel about salvation is NOT what applies today under the Gospel of Grace. We are saved by grace through faith, period, and that not ourselves, lest any man should boast, but a gift from God. Adding to that what was meant only for us Jews at that time, that's stealing what you Gentiles clearly should not want for yourselves. None of us is saved on the basis of effort or works, and thinking one must maintain salvation on the basis of works and/or refraining from certain sins, that is STILL works-based salvation, which cannot save anyone.
