What does the Bible say about complaining?

Just innocently venting your frustrations, or has your complaining crossed the line into outright spiritual disobedience? When looking at what the Bible says about complaining, there is a sharp contrast between pouring out healthy, biblical grief to the Lord and the sinful grumbling that exposes a destructive lack of faith. From the Israelites murmuring in the wilderness to the smoldering discontent that kills our peace today, unchecked fault-finding is ultimately an accusation against God's sovereign provision. Watch to see where the line is drawn, and learn the scriptural steps to conquer a complaining spirit so you can faithfully "count it all joy" (James 1:2, ESV) in every circumstance.
