An elderly sister pointed to the printed out pledge forms on the literature counter and asked me what this was about, because she'd missed a couple of meetings.
I tactfully (and very quietly!) explained that there was a new donation arrangement via pledging! I quickly explained to her that the congregation donation amount had already been announced, so there was no need for her to fill out a pledge slip. All she had to do was donate what her heart told her to do. I told her what Deuteronomy 23:21,22 says about making vows and not fulfilling them, so she would do better by NOT making a vow!!
She thanked me for explaining things and said she wouldn't fill in the slip!!! Result!!!
