I read newspaper articles and write to the editor when they're poorly written. I correct people's grammar in online forums. I get angry when my daughter's school contantly incorrectly uses apostrophes.
But when I got this card from my daughter (which has a grammar mistake), I did not care about the grammar. I did not chide her for her poor grammar. I gave her a hug and had a little cry. And I've kept it proudly on my desk (happily uncorrected).
Why? Because I love her, and I can see the love behind it.
Got friends who have strong views on Christianity? Or who constantly argue with you about your faith (or theirs)? Living in a situation where you're reaching people or planting churches? Perhaps there's a place for correction. But surely we must reserve the #1 place for love - because
Love never fails! Everyone who prophesies will stop, and unknown languages will no longer be spoken. All that we know will be forgotten. We don't know everything, and our prophecies are not complete. But what is perfect will someday appear, and what isn't perfect will then disappear. (1Co 13:8-10)
