Hey Nancy. :) I'm going to give you my reasons but I think it requires a bit of my life story so bear with me a bit here lol.
I hear what you're saying for sure. I struggled for a long time trying to figure out who was telling the truth, who was lying, and who was being deceived of those who claimed to have revelations from God. The thing is before church doctrine such as calvinism started being driven into my head, I could hear Him quite well. I knew His voice and His nature and I was learning from Him. But I started listening to the preachers and teachers instead of His voice. I have no idea why... thinking back it's like, DUH, that was stupid lol! So instead of believing in His loving voice, I started to believe what the preachers said: He "chose" me to go to heaven and most of my family to go to hell. (None of my immediate family were Christians at that time.) I stopped being able to discern His voice very well because I had such a skewed view of His nature. Anyhow, I got to the point where I just couldn't bear the thought of hell anymore, it was after my daughter was born, I just couldn't imagine God ever letting her burn forever (or even for a short amount of time), I knew in my heart it wasn't right, I knew that it wasn't love, yet there were all these books and NDE's and visions that people claimed to have had about this horrible, fiery, tormenting place where God supposedly either throws or allows mankind to be thrown into. So I cried out to Him, "Lord what is the truth??? If hell is somehow good please show me!" I hadn't even thought about Universal Reconciliation, it had never occurred to me that was even an option. But I went to the library shortly after that prayer and randomly picked up three books. Each of those books either openly taught or hinted at Universal Reconciliation. There was nothing on the cover or description that would suggest any of those books even had anything about UR in them. I was like, OOOOOKAY I get it Lord lol!
Shortly after that there was a link on the side of my email to a website by a man who claimed to hear from the Lord. One of the things he claimed was that God wanted him to share that all people would eventually be saved, no matter how much persecution he had to get over that doctrine. (And as I'm sure you can guess, he likely gets a lot.) His website said "From the Voice of the Lord". At first I was VERY hesitant, I almost didn't read it because I had read so many people who claimed to hear from God who were very obviously crazy or worse... But I gave it a go and what he had to say really resonated with my spirit. It was like I had FINALLY found what I was looking for. (His website is hallvworthington.com in case you're wondering.)
Anyhow, at that time I was also reading here on TM. I started paying close attention to what Cardinal had to say because even though most of it went completely over my head, a lot of it also resonated with my spirit. I started searching her posts and realized, WOW, she is saying the exact same things as Hall is saying on his site, and she also claims to hear from God directly! Not only did Card have the same revelations from God that Hall had, she also had the signs and wonders to go with it. (God has healed people through her, given her words of prophecy, words of knowledge, discerning others thoughts, etc, etc.) But more than that, as I got to know the both of them, one thing REALLY stood out and that was that they both had the love that Christians are supposed to have! (By the way, they have never met, never talked, never emailed, nothing. Yet they both hear the same things from the Lord.) I started realizing that there are many more people who hear from God and they also teach the same things. It was like a major lightbulb moment for me and I was so excited lol.
The major thing for me is, both Hall and Cardinal taught that we need to go to Him ourselves to be taught of Him ourselves. HE is the teacher, and HE will lead us into all truth! It was like "OOOOHHHHHH YEAHHHHH!!!" LOL. Because that is what I had been doing at the start of my Christian walk. Once I left the church and started going to God again for truth, He started to show me the same things He has shown Cardinal and Hall, and He is beginning to free me from things that are holding me in bondage, which Hall and Card said He could do.
I now know Cardinal very well, she is one of my dearest friends and I believe every word of what she says, because a) she has the experiences to back up what she is saying, b) she has the love that Christ said His true followers would have, c) she has been shown the exact same things as Hall and others, and d) because God has shown me many of the same things He has shown her.
As for the stigmata woman; I have no idea what sort of a sign that is... I mean in the Bible His disciples signs were healing people, casting out demons, those sorts of things, not things such as stigmata marks, you know what I mean? To me now, it is fairly easy to see who is real and who is fake. The Lord will show us all of these things. :)
God bless you as well!
