And all the people of Israel grumbled.Numbers 14:2
There are grumblers among Christians now, just as there were in the camp of Israel of old. There are those who, when punished, cry out against the affliction. They ask, "Why am I afflicted? What have I done to be chastened in this manner?"
A word with you, grumbler! Why should you grumble against the dealings of your heavenly Father? Can He treat you more severely than you deserve? Consider what a rebel you once were, but He has pardoned you! Surely, if He in His wisdom considers it necessary to chasten you, you should not complain. After all, are you punished as severely as your sins deserve? Consider the corruption that is in your heart, and then will you wonder that so much of the rod is necessary to root it out? Weigh yourself, and discern how much dross is mingled with your gold; and do you think the fire is too hot to purge away the amount of dross you have? Doesn't your proud rebellious spirit prove that your heart is not thoroughly sanctified? Aren't those grumbling words contrary to the holy, submissive nature of God's children? Isn't the correction necessary?
But if you will grumble against the chastening, pay attention, for it will go hard with grumblers. God always chastises His children twice if they do not respond properly the first time. But know this--"He does not willingly afflict or grieve the children of men."1 All His corrections are sent in love, to purify you and to draw you nearer to Himself. Surely it must help you to bear the chastening with submission if you are able to recognize your Father's hand. "For the Lord disciplines the one he loves, and chastises every son whom he receives."2 ". . . nor grumble the way some of them did and were destroyed by the Destroyer."3
