As an Israeli, I was taken in by the modern Messianic Jews, but deep down I knew something wasn't right. We talked much about Tenakh and very little in the four gospels, and almost never in the rest of what Gentiles referred to as the rest of t B e "Nes Testament." Passing from Judaism into Messianic Judaism was quite a transition, but what's sad is they are still lost while relying upon adherence to select portions of the Law for their works as a supplement to their sense of mmsalvation.
For example, they experienced episodes of uncertainty that they spoke of only among fellow Messianic Jews, never in mixed company. The lack of assurance as to if they have done enough obedience to Torah to truly have tapped into the good graces of Christ for their salvation. They have no trust for Paul, considering him to be a renegade who was not a true apostle for teaching salvation by grace through faith alone. They refuse to believe in that hope Paul taught, which is OSAS.
Yes, we had no doubts Paul taught that once a person was saved, their salvation is everlasting. Many modern Evangelicals may doubt Paul taught that, which he clearly did as we knew by way of our Hebrew and Greek (Septuagent) as well as Coine Greek literacy, but our culture grated against that truth because of Torah having been so deeply ingrained within us.
We do have insights quite removed from the Western mindset and way of thinking, with vastly differing idioms, but that doesn't make us superior to anyone, even though many in the ranks of Messianic Judaism think otherwise. Paul became my tutor in that regard. His way of thinking and his reasoning was and is so vastly humble and yet superior to what was before and what will be...even though it wasn't just him speaking. Therein is the reason I marvel at all the loss of salvation gang members out there who beat themselves and others up over that patiently false doctrine, teaching Messianic Judaism style trash to others. That pleases the enemy of our souls greatly.
Our brothers, the twelve, preached truth, but not all their truths were meant for us today. Israel is fallen, and that alone shows the difference.
