Yet I will rejoice in the LORD, I will joy in the God of my salvation. – Habakkuk 3:17

Brethren, if the Lord does not answer the prayer which we are offering, yet still He is so good, so supremely good, that we will bless Him whether or no. We ought even to praise Him when He does not answer us, ay, and bless Him for refusing our desires. How devoutly might some of us thank Him that He did not answer our prayers when we sought for evil things in the ignorance of our childish minds. We asked for flesh, and He might have sent us quails in His anger, and while the flesh was yet in our mouths His wrath might have come upon us; but in love He would not hear us. Blessed be His name for closing His ear in pity! Let us adore Him when He keeps us waiting at His doors; thank Him for rebuffs, and bless Him for refusals…Ralph Erskine spoke the truth when he said:

“I’m heard when answered soon or late,
Yea, heard when I no answer get:
Yea, kindly answered when refused,
And treated well when harshly used.”

Faith glorifies the love of God, for she knows that the Lord’s roughest usage is only love in disguise…Though He slay us we will trust in Him, much more if He decline our requests. We ask Him for our daily bread, and if He withhold it we will praise Him. Our praises are not suspended upon His answers to our prayers. If the labour of the olive should fail, and the field should yield no fruit; if the flock should be cut off from the fold, and the herd from the stall, yet still would we rejoice in the Lord, and joy in the God of our salvation. Blessed Spirit, raise us to this state of grace and keep us there. ~ C.H. Spurgeon
