I've got a few. I won't say too few to mention, but I will tell you one of mine.
I regret that I didn't work out how to brush my teeth until well into adult life. Don't rush to me with sympathy; my teeth are ok, but there's been a lot of work in mouth that predates the dentist carefully explaining the best way to brush and floss. When my children were young my catchphrase was 'every bit of every tooth,' a lesson I learned the hard way.
This week is our harvest service and we are supporting a project organised by Operation Agri in Nepal. They do a lot of things; one is that they teach children to take care of their teeth. They also teach them what they should do in an earthquake and many other things.
I didn't know that I was brushing my teeth incorrectly, but boy did I notice the difference when I started getting it right.
Jesus tells us to come and learn from him. I wonder what else I'm doing wrong. I wonder what I need to hear from him. Maybe the work of Operation Agri will help me find out.
