"all have sinned and come short of the glory of God" (Romans 3:23)
All includes Mary, What satan often will do ... Is get some truth ... and stretch it beyond truth to an extreme to what is a final product called "Half-Truth" ... Half-truth's are more dangerous than white lies.
RomeSweetHome: Mary in my opinion did her part and just gave birth to Jesus, she was a sinner too. Satan often tries to make Mary seem like a god or part of the trinity, but she was just a women too.
Romans 3:23 Declares that ALL have sinned, including mary.
If Mary was Sinless ... She could have also died on the Cross for our sins, because to be able to forgive sins ... You would need to be sinless. So for people that may claim Mary was sinless, she could have also died on the cross, but she didn't, because that was not Gods plan, that's why he sent his only begotten son (John 3:16)
Mary was just the mother, nothing more. If the Bible wanted to focus on Mary it would have mentioned her alot throughout the scriptures and gave glory to her, but we see the Bible talks more about Jesus, not mary.
My friend ... Jesus loves you, he wants you to come to know the truth ... he said ... "I am THE way, THE truth, and THE life, no man cometh unto the Father but by ME"
