Sisters in Christ  are all those ladies who have been born again like yourself.  When we are born of God, like you were, then God is your Father, and all real Christians (those born again and living for Him) are then your sisters and brothers because you have been born into the family of God!  So you are Arlyn’s sister and I am your brother and you are my sister!  We are all family now.

You are sisters of everyone THAT ARE BORN AGAIN, not of the worlds people, but those in the church.
