[Salvation]

I sure you have Luke's greeting of the Archangel Gabriel, the Lord's messenger to Mary:

"Hail Mary, full of grace,"

Now, how can she be full of grace if she had sinned?

Again a simple answer -- right there in Holy Scripture!

[PugetSoundSoldier]

Please see Acts 6:8 - Stephen is not considered sinless, yet the Bible plainly states that he was full of grace and power.

There is no condition on being sinless to receive the grace of God; in fact, God’s grace is what makes us sinless.

"Grace" (in Christian belief) the free and unmerited favor of God, as manifested in the salvation of sinners and the bestowal of blessings.

Yes, it is a simple answer, but it is not the one you promote.

God didn't say she was full of grace...That's an addition by your religion...
