Let me add my 2 cents.. I am going to be broke adding my 2 cents so many times all over the place!
Let's look at it Biblically.. I would look at 2 verses.. Paul clearly states that anyone who call on the Lord will be saved.. Salvation is available for everyone.. He is not saying a sound doctrinal understanding is needed and so on.. Simply calling upon the name of Lord.. I will link this with the woman with bleeding for 12 years.. She does something totally crazy.. We see she thinks all she has to do be healed is touch Jesus' garment.. And we see Jesus later saying she was healed by her faith.. But there is nothing in OT or Jesus's teaching which says that by touching his garment one could be healed.. Can I take a step and say she was not doctrinally strong? or take one more step and say she was doctrinally wrong? All that mattered was faith that Jesus can bring healing..
I am not saying it means it is okay to be wrong doctrinally. I am just saying, God looks at heart like no man does.. God will always honor the faith of a person (not to say result will be as we expect, but result will be for His glory)..
This is what leads me to believe that anyone who calls upon the Lord and has faith, will be honored by Lord..
Romans 10:12-13
For there is no distinction between Jew and Greek; for the same Lord is Lord of all, abounding in riches for all who call on Him; for "WHOEVER WILL CALL ON THE NAME OF THE LORD WILL BE SAVED."
Mark 5:25-29
A woman in the crowd had suffered for twelve years with constant bleeding. She had suffered a great deal from many doctors, and over the years she had spent everything she had to pay them, but she had gotten no better. In fact, she had gotten worse. She had heard about Jesus, so she came up behind him through the crowd and touched his robe. For she thought to herself, “If I can just touch his robe, I will be healed.” Immediately the bleeding stopped, and she could feel in her body that she had been healed of her terrible condition.
Sorry for my bad humor.. Just trying to bring the tension down.. I know, I am not good at it
