I heard a preacher make this statement in a sermon. “The Israelites went to Moses with complaints about God. Moses went to God with complaints about the Israelites.” Then he explained that if you are going through a difficult season, be like Moses and not the Israelites.
While the statement is an oversimplification, it does capture the truth in a memorable way. Being unhappy is not an issue when life gets tough, and you walk through a season of pain. The concern is what you do with your unhappiness.
Do you talk to others and voice your struggles to them more than God?
Difficult times are inevitable; use them to grow closer to God and not create a division with him when you complain.
