Is Mary Your Mother?

She is if you keep God's commandments and bear witness to Jesus.

A great sign appeared in the sky, a woman clothed with the sun, with the moon under her feet, and on her head a crown of twelve stars. She was with child and wailed aloud in pain as she labored to give birth. ... She gave birth to a son, a male child, destined to rule all the nations with an iron rod. Her child was caught up to God and his throne. (Revelation 12:1-2,5)

The first part of the twelfth chapter of the Book of Revelation tells us about a woman and her son. The son who is destined to rule the nations and caught up to God is clearly Jesus and so the woman can only be Mary. We are told of a dragon, and that the dragon is Satan, and of how the dragon pursued the woman but could not catch her.

Then the dragon became angry with the woman and went off to wage war against the rest of her offspring, those who keep God's commandments and bear witness to Jesus. (Revelation 12:17)

The Bible could not be clearer. Those who keep God's commandments and bear witness to Jesus are Mary's "Offspring".
