Grumbling and complaining. There is nothing worse than to have to listen to another person constantly grumble and complain. It's like fingernails on a chalk board, a dripping faucet, barking dogs in the middle of the night, or even worse... whining children. We all hate it when it comes from someone else but why do we do it ourselves? Why do we think of it as just a minor thing that's really not so bad?
How serious do you think it is when we complain? Let's see what God says.
Do all things without complaining and disputing. Philippians 2:14
Now when the people complained, it displeased the Lord; for the Lord heard it, and His anger was aroused. So the fire of the Lord burned among them, and consumed some in the outskirts of the camp. Numbers 11:1 (ouch!)
How long shall I bear with this evil congregation who complain against Me? I have heard the complaints which the children of Israel make against Me. Numbers 14:27 (congregation plus complaining against God equals evil. HMMMMMM...)
The carcasses of you who have complained against Me shall fall in this wilderness, all of you who were numbered, according to your entire number, from twenty years old and above. Numbers 14:29 (carcasses? As in dead bodies. Yep.)
Therefore I will not restrain my mouth; I will speak in the anguish of my spirit; I will complain in the bitterness of my soul. Job 7:11 (not restraining the mouth leads to anguish of the soul which leads to more complaining which then results in bitterness. I am beginning to see a trend.)
In 1 Corinthians, Paul tells us: Moreover, brethren, I do not want you to be unaware that all our fathers were under the cloud, all passed through the sea, all were baptized into Moses in the cloud and in the sea, 3 all ate the same spiritual food, and all drank the same spiritual drink. For they drank of that spiritual Rock that followed them, and that Rock was Christ. But with most of them God was not well pleased, for their bodies were scattered in the wilderness. Now these things became our examples, to the intent that we should not lust after evil things as they also lusted. And do not become idolaters as were some of them. As it is written, "The people sat down to eat and drink, and rose up to play."
Next, Paul goes on to say this: Nor let us commit sexual immorality, as some of them did, and in one day twenty-three thousand fell; nor let us tempt Christ, as some of them also tempted, and were destroyed by serpents; nor complain, as some of them also complained, and were destroyed by the destroyer. 1 Corinthians 10:1-10 Paul is listing the failings of the children of Israel, and ends with saying that some of them complained and they were destroyed by the destroyer. Don't let this slip by! Now, who was this destroyer? Go to Revelations 9:11. And they had as king over them the angel of the bottomless pit, whose name in Hebrew is Abaddon "Destroyer", but in Greek he has the name Apollyon "Destruction".
A word of caution, guard your tongue.
Guard your heart.
Guard your mind.
When you open the door to complaining and grumbling, you open the door to hell... you welcome in the Destroyer and the destruction begins.
