Charles H. Spurgeon on Psalms 119:42

So shall I have, etc. I shall have something by which I may reply to those who calumniate me. So the Saviour replied to the suggestions of the tempter almost wholly by passages of Scripture (Matthew 4:4, Matthew 4:7, Matthew 4:10); and so, in many cases, the best answer that can be given to reproaches on the subject of religion will be found in the very words of Scripture. A man of little learning, except that which he has derived from the Bible, may often thus silence the cavils and reproaches of the learned sceptic; a man of simple hearted, pure piety, with no weapon but the word of God, may often thus be better armed than if he had all the arguments of the schools at his command. Comp. Ephesians 6:17. Albert Barnes.
