As the daughter of a mom who enables me in any endeavor I set my sights on, I am very inclined to believe that the woman in your church is just like my mom.
Mom and I can walk through the same garage sale and SHE will be the one to find a grand sewing machine for $45 and bargain the person down to $35 and find a shoe box full of rickrack and binding for 75 cents. She doesn't sew, but because she knows I do, she will show me where the good buys are, then buy everything.
She encourages a lot of people with her ability to find deals and when she finds out someone needs something for a good cause, you can bet Mom is on the "hunt" for their supplies.
Because she was once a young mom and wife, she remembers tight budgets and understands that she has time to find the buys, while others are busy with a productive life.
All one has to do, if you are around my mother, is tell her about a project you are working on, and my mom will be around with an armload of supplies ... all purchased at a good price.
She does it because she believes that she is using her gifts and resources to the best of her abilility to glorify the Lord.
Her generosity springs from appreciation for others who do what she cannot do.
She, who cannot sew, knit, or crochet, has been my biggest cheerleader, and is always looking for others who do the same things I do, to encourage them. She is generous so that others may be also. 3 John 4
when mom was a young wife, my dad's mother did a lot to help mom and dad accomplish their goals. She babysat, sewed clothes, she invited them to meals ... I was very young <g> I don't know what all grandmother wright from Oklahoma did for my family, but mother shared a conversation she had early on with her mother-in-law:
She asked: You do so much for us. How will I ever be able to repay you for all you have done?
Grandmother answered: You can't. But, there will be a time when you will be able to help someone else. Always remember that at one time, someone helped you - - and pass it on.
(Trust me - - this was DECADES before "Pay it Forward".
Rest your mind, my dear. I am certain you just found a benefactor who understands give and take ... the best thing you can do after you say "THank you" is to pass it on by using your gifts to bless others.
