Complaining is a Sign of Being Ungrateful
Yes, we have all done it from time to time. Things don’t go our way and we are complaining about this and whining about that. We make excuses. Yet the Bible clearly says that complaining is a sin. It is shows an attitude that you are ungrateful and bitter. It often tests God’s patience.
1 Corinthians 10:10 - And do not grumble, as some of them did—and were killed by the destroying angel. (NIV)
Job 10:1 - I loathe my very life; therefore I will give free rein to my complaint and speak out in the bitterness of my soul. (NIV)
Complaining Can Lead to Disobedience
While the Bible says that complaining is a sin, it also states that it can lead to further disobedience. Along with complaining comes pouting. If you complain too much or focus on all the negative things, you can lose sight of all the good things God does in your life. This can lead to an attitude where you lose faith and cause others to lose faith, too.
Psalm 106:25 - They grumbled in their tents and did not obey the LORD. (NIV)
Keep a Positive Attitude
Things will go wrong in your life. A pop quiz. A long term paper. A break up. A fight with your friend. These things happen. You can spend your time complaining, taking your eyes off of God, or you can find a way to make things better. You can remember all the other things God has provided. Not only will you be happier, but you will be a positive Christian example to everyone around you.
Ephesians 4:29 - Do not let any unwholesome talk come out of your mouths, but only what is helpful for building others up according to their needs, that it may benefit those who listen. (NIV)
