Very good discussion in another thread about whether a person can be saved without understanding the resurrection.
Accept, for this thread, no one is saved without God Holy Spirit involvement and salvation is through faith in Jesus.
The question is….. what is the “gospel”? At a minimum, what is enough info to qualify as a presentation of the Gospel whereby God Holy Spirit convicts the unbeliever of the truth that Jesus is their Savior by faith.
In other words, if you leave “this part” out of your presentation, it is no longer the “gospel” and God Holy Spirit will not work to bring that person to salvation.
I'd have to think about this passage and how much she knew.
WE KNOW SHE WAS SAVED. Jesus said it.
Luke 7:36-50
36One of the Pharisees asked him to eat with him, and he went into the Pharisee’s house and reclined at table.
37And behold, a woman of the city, who was a sinner, when she learned that he was reclining at table in the Pharisee’s house, brought an alabaster flask of ointment,
38and standing behind him at his feet, weeping, she began to wet his feet with her tears and wiped them with the hair of her head and kissed his feet and anointed them with the ointment.
39Now when the Pharisee who had invited him saw this, he said to himself, “If this man were a prophet, he would have known who and what sort of woman this is who is touching him, for she is a sinner.”
40And Jesus answering said to him, “Simon, I have something to say to you.” And he answered, “Say it, Teacher.”
41“A certain moneylender had two debtors. One owed five hundred denarii, and the other fifty.
42When they could not pay, he cancelled the debt of both. Now which of them will love him more?”
43Simon answered, “The one, I suppose, for whom he cancelled the larger debt.” And he said to him, “You have judged rightly.”
44Then turning toward the woman he said to Simon, “Do you see this woman? I entered your house; you gave me no water for my feet, but she has wet my feet with her tears and wiped them with her hair.
45You gave me no kiss, but from the time I came in she has not ceased to kiss my feet.
46You did not anoint my head with oil, but she has anointed my feet with ointment.
47Therefore I tell you, her sins, which are many, are forgiven—for she loved much. But he who is forgiven little, loves little.”
48And he said to her, “Your sins are forgiven.”
49Then those who were at table with him began to say among themselves, “Who is this, who even forgives sins?”
50And he said to the woman, “Your faith has saved you; go in peace.”
Maybe she knew he was the Messiah. She definitely did not know about the resurrection.
