Complaining. There's room for legitimate complaining, but if you let this deadly disease of attitude – complaining - loose it will conquer you. Complaining can take over your life. Destroy you and leave you without anything. Nobody wants to take along a complainer. Nobody wants to promote a complainer. Nobody wants to live with one. Nobody wants to be a partner of one. Nobody wants to have one around. Complaining leaves you out of more opportunities than you can possibly imagine if you let it take over and grab you by the throat. If you don't think complaining is bad ask the children of Israel of Old Testament fame. They are typical of us all, but their story just happened to get in the Book.
The story says children of Israel are slaves in Egypt. God performed a series of dazzling miracles and gets them out. Now they have their freedom and are heading for the Promised Land. But... the tragedy of the story - they never got there. Reason - from day one they started to complain. They griped about the food - they had just been delivered from slavery and they are complaining about the food?! They whined and cried and griped about the water. In the desert they HAD water to drink, but... it didn't taste that good?! They whined and complained about the leadership... that had just delivered them from slavery?! They complained that it was too hot, too cold, too far, too difficult, too rocky. They whined and cried for years - forty to be exact.
Finally, God said I've had it - Trip Cancelled!
