If ye endure chastening, God dealeth with you as with sons; for what son is he whom the father chasteneth not? “As many as I love, I rebuke and chasten: be zealous therefore, and repent.” – Hebrews 12:7; Revelation 3:19

There is not a more profitable instrument in all God’s house than the rod. No honey was sweeter than that which dropped from the end of Jonathan’s rod; but that is nothing to the sweetness of the consolation which comes through Jehovah’s rod. Our brightest joys are the birth of our bitterest griefs. When the woman has her travail pangs, joy comes to the house because the man-child is born; and sorrow is to us also, full often, the moment of the birth of our graces. A chastened spirit is a gracious spirit; and how shall we obtain it except we are chastened? Like our Lord Jesus, we learn obedience by the things which we suffer. God had one Son without sin, but He never had a son without sorrow, and He never will have while the world stands. Let us, therefore, bless God for all His dealings, and in a filial spirit confess, “Thou, Lord, hast chastened me.”

“If God appoints the number ten,
There ne’er can be eleven.”

Whenever the Lord mixes a potion for His people, He weighs each ingredient, measures the bitters, grain by grain, and allows not even a particle in excess to mingle in the draught. Like a careful dispenser, He will not pour out a drop too little or too much.

“To His Church, His joy, and treasure,
Every trial works for good:
They are dealt in weight and measure,
Yet how little understood;
Not in anger,
But from His dear covenant love.”

~ C.H. Spurgeon
