…Thy word was unto me the joy and rejoicing of mine heart… – Jeremiah 15:16

He who has spiritually found God’s word, and consequently feeds upon it, is the happy man. But in order to get joy from God’s word we must receive it universally. Jeremiah first speaks of God’s “words,” then he changes the number and speaks of God’s “word.” We are not only to receive parts of the gospel, but the whole of it, and then it will afford us great joy. That man’s heart is right with God who can honestly say that all the testimonies of God are dear to him. “But” saith one, “that is impossible: parts of the Bible are full of terrible denunciations; can they afford us joy?” In this way, brethren: if God appoints that sin should be punished, we are not to rebel against His righteous ordinance, nor to close our minds to the consideration of divine justice; God’s judgments are right, and what is right we must rejoice in. Moreover, by the threatenings of His word many are led to forsake their sin, and thus the warning itself is a means of grace. To tender-hearted Jeremiah I have no doubt it was a trial to say, “Your city will be destroyed, and your women and your children will be slain.” But when he considered that some might be led to repentance, he would with tearful vehemence deal out the thunder of the Lord. But, brethren, God’s word is not all threatening. How much of it consists of exceeding great and precious promises? Grace drops from it like honey from the comb. How would even Jeremiah brush away the falling tear, while that face usually so clouded would beam as the sun when he spoke of the Messiah? Surely, if there be anything in the whole range of truth which can make our hearts leap for joy, it is the part of it which touches upon the lovely Person and finished work of our adorable Redeemer, to whom be honor and glory for ever. Receive the whole of God’s word. Do not cut a single text out of Scripture or desire to pervert its meaning. Hold the truth in its entirety and harmony, and then as a matter of certainty it will become to you the joy and rejoicing of your spirit. ~ C.H. Spurgeon
