I found this verse in my readings this morning and I smiled because even though I can't remember ever reading this verse before God gave me this message years ago.
I worked in a convience store and would always ask "How are you today?" more often than not I was sorry for asking right away. One of my friends would come in every night and she NEVER had a good day. Sadly I found myself thinking of bad things that happened to me when I saw her walk in because I wanted to have a worse day than her. It took me a while to realize what I was doing but God conviced me. One night when she walked in and asked how my day was, I said WONDERFUL...she looked at me, blinked and said "mine too". Wow, I think I might have held my breath for a minute. Would I say wonderful and then have to listen to a litany of her bad day? I'm amazed to this day how often a smile and a WONDERFUL can stop a complainer in a blink...It stops me if no one else.
Follow Pauls instructions in the Bible...Do everything without complaining and arguing. See how much better it makes your day
