FTR, my best friend NEVER did drugs, I have never seen her have more than one drink an evening (and even that is rare) in the 10 years I have known her, she works 2 and sometimes 3 jobs to take care of her invalid mother, squeezes church and charity work in between those jobs and is one of the most generous people I know even BEFORE she was a Christian.
Now, she is even more so and what changed aside from her beliefs (she was an atheist), is her motivation. She now does it solely for the glory of God.
This is wonderful news that she has accepted Christ.
I bet that she doesn’t deliberately set out to offend others and their customs but is, instead, meek and loving to all.
