Well, as shocking as it is that devoted old ladies could be guilty of sin (gasp) just as much as any other man, woman, or child. . .
Change is inward, not outward, and it is not limited to feelings (feelings are notoriously unreliable taken solely by themselves). I venture to say that if you concentrate on knowing, loving, and serving God AND loving your neighbor as yourself, you will indeed not just feel but truly understand the change as you become a servant of God and a member of His Body.
Are you worried about these ladies because you wish them to know, love, and serve God, and to love others, and want to help them and have them help you–
or are you more concerned that if these “pillars” are just ordinary sinners, maybe you’re chosen the wrong church, because surely the “right church” would only have perfect people in it?
Think about it.
We are all sinners. And we all fall short. Thing is, when I fall, I would SO much rather have somebody raise me up with kindness, understanding, and sympathy, as an equal. . .than to have somebody, in the guise of “raising” me, treat me as a leper, a pariah, or something disgusting on a shoe bottom, as though they were gold and I was. . .well, dirt.
