In Numbers 11 we see a group of discontents bad-mouthing God’s provision. They wanted more than manna, they wanted meat! “If He truly loved us, He would give us what we WANT, not merely what we need!” and this sentiment spread among the people. We have very little trouble becoming self-focused. We are actually quite good at it.
If I’m being honest, I don’t really understand why they needed God to provide above what he had already given them, we know they had herds and livestock, and we know in the case of AT LEAST Peace Offerings, they ate those animals.
In either case, God decided to give the people what they wanted. I’ve heard it said that “God is a gentleman”, in that He will not force His will upon you (my Calvinist brothers and sisters would disagree, so for their sake, maybe I’ll just say it’s explained by “tension”). Essentially this means that if we do not come before God and pray, “let Your will be done”, then He will — with great sadness — give you over to the desires of Your heart and let your will be done.
Such is the case here. God sent the Israelites an exceptional amount of quail. And they caught it and ate it and they were fat and satisfied… until it made them sick. And more than that, the instigators DIED as a result of this tainted bird.
Don’t spit on God’s provision. He has giving you what you need to accomplish His will. Be satisfied with what you have and steward it well. If you do, then He will continue to trust you with more and more. But if you chose to complain about what God has done, don’t be surprised if He stops giving you gifts that you don’t appreciate anyway.
