Yes, I agree Loquat! God can open the eyes of anyone, anywhere, even someone sitting in the middle of a cult service somewhere.
Keeping the seventh day Sabbath and the biblical Holy Days, these practices were the big deal in the cult I grew up in and we felt pretty good about our salvation because of all that, and of course being in the one true church, which was us and nobody else. :( But I remember thinking one day sitting in one of the services that there were so many other things I wasn't doing right, and it begin to dawn on me from then on that there was no way my salvation was secure just because I was keeping the Sabbath, etc. which now I know I wasn't really keeping anyway.
So for the next several years, I believe God began to open my eyes more and more to my true need and hope for salvation, Jesus! Nothing I was doing was going to cut it. I went through a lot of fear as a result of these realizations until I finally understood the true gospel, which set me free. But I believe God was starting to pull me out of that false religion even while I was still sitting there in the services.
And the same for my dad. He started reading the bible for himself while still sitting in the cult services, and then he started to see the bible's teachings were different than the cult's teachings, radically different.
So yeah, by the grace of God, there is hope for anyone, anywhere, to come to the true gospel.
I've been accused a lot on here of hating people in
certain groups or denominations, but it's just flat out not true. I just want to expose the false teachings and see people in whatever group or denomination they are in, come to the true gospel. I was deceived and in a false religion for many years of my life, so why would I have hatred for people who are no different than I was? But the bible speaks very harshly about those who lead others astray, especially those in high leadership positions, and so these people in those leadership positions need to be exposed. Herbert W. Armstrong needed to be exposed, and I'm so glad for my sake and countless others out there, that many began to take a stand against him, and expose him, and now many of us are free from that false religion.
So while we were putting a lot of trust in the keeping of the Sabbath and Holy Days and being a part of that particular group for salvation, you could put whatever else in the place of that, and it's all the same thing. If it's not Jesus and his finished work alone someone is trusting in for salvation, it's not the right thing, and there's no security in it!
