?How many times today have you complained?  “I remembered God, and was troubled;I complained, and my spirit was overwhelmed. Selah”. Psalm 77:3

Complaining is a sign of a heart that needs healing.  

Complaining displeases and angers God (Numbers 11).   Take everything to God.  He can work on your behalf.  

“Do all things without complaining and disputing,”  Phil 2:14
