Grumbling is not a fruit of the Spirit

 And when they saw it, they all grumbled, "He has gone in to be the guest of a man who is a sinner."

Luke 19:7 (ESV)
 
When God is not about me the way I want Him about me, I grumble. I sometimes do more than grumble. I outright complain, and may even doubt God's existence and love.
 
Imagine doubting someone's very existence because they do not act per your expectations. Imagine getting angry with someone because they have given attention to someone else over yourself.
 
We seem to be slow learners in that we struggle with the same issues today as we did hundreds of years ago. We want God to be about us when we should be about Him. We want our "religion" to make us unique rather than our repentance. We like to focus on us when we should be focusing on Him.
 
Religious people are grumpy people because their focus keeps life out of focus, and causes them to run into all sorts of obstacles that clarity would have avoided. Grumbling and discontent are not fruits of the Spirit and indicate wrong focus and thinking. Perhaps there is still time to make things right.
