Thanksgiving Day, I will be a turkey tick - ready to pop. I do like the Thanksgiving meal...and football. But there is more to the holiday than getting fat and vegging out.
I'm thankful for what I got. Being thankful is healthy. Withholding thanks, appreciation and so forth is emotionally similar to being insulted and just taking it - and not in the Jesus way. When a person receives, there is an emotional reality that refuses to go unexpressed. Sadly, when we withhold appreciation, it rots inside us and degrades into selfishness (and becomes intolerable), into greed (and becomes insatiable), or into depression (and becomes inconsolable).
Withholding thanks gets you emotionally constipated real fast. Thanksgiving is the soul's laxative.
