Overlooking the error of him refusing to read other books... this stands between Spurgeon on reading more Bible and his words on Paul and his books..
"Libraries make swelled heads, but the Word of God makes enlarged hearts. We are to have enlarged hearts, hearts fiolled with the fragrance of the love of God that will show forth the life nad power of the Lord. Faith cometh by hearing, and hearing by the Word of God - not by reading commentaries. Faith is the principle of the Word of God. The Holy Spirit, who inspired the Word, is called by the Spirit of truth; and as we receive with meekness the engrafted Word, faith springs up in our hearts; faith in the sacrifice of Calvary; faith in the shed blood of Jesus; faith in the fact that He took our weaknesses upon Himself, that he has borne our sicknesses and carried our pains, and that He is our life today. The Word of God is living and powerful, and in its treasure you will find eternal life. If you will dare to trust this wornderful Lord of life, you will find in Him everything you need... I have never read any book but the Bible... Fill your head and your heart with the Scriptures.... as you do this, you are sowing in your heart seeds which the Spirit can germinate.... You must be soaked with the Word of God, you must be so filled with it... Believers are strong only as the Word of God abides in them... Know your Book, live it, believe it, and obey it. Hide God's Word in your heart. It will save your soul, quicken your body, and illumine your mind. The Word of God is full and final, infallible, reliable, and up-to-date, and our attitude towards it must be one of unquestioned obedience. If a thing is in the Bible it is so; it is not even to be prayed about; it is to be received and acted upon. Inactivity of faith is a robber which steals blessing. Increase comes by action, by using what we have and what we know. Your life must be one of going from faith to faith.... Because you dare to believe, you act in obedience.p73-75. Smith Wigglesworth, Apostle of Faith by Stanley Howard Frodsham. The book itself is something of a hagiography but Wigglesworth clearly had some good stuff to say
