Though he’s not as well known as some other evangelists of his era, the legacy of Smith Wigglesworth has had a major influence on modern Evangelicalism. Born in 1859 in England, Wigglesworth came from a working-class family. He didn’t learn to read until he was an adult. But after reading the Bible for himself, he dedicated his life to traveling, preaching and ministering.

Though he was a student of Scripture, Wigglesworth is probably best known for his role as a faith-healer—employing methods of prayer and deliverance in his services that were sometimes controversial.

An important figure in the modern Pentecostal movement, Wigglesworth has had his critics. But, his embrace of the supernatural and his belief in the miraculous is also what makes his writings so challenging.

Here are 13 Smith Wigglesworth quotes that will challenge your ideas about faith.

On Faith

“There is nothing impossible with God. All the impossibility is with us when we measure God by the limitations of our unbelief.”

On the Holy Spirit

“The Spirit reveals, unfolds, takes of the things of Christ and shows them to us, and prepares us to be more than a match for Satanic forces.”

On Difficult Times

“Great faith is the product of great fights. Great testimonies are the outcome of great tests. Great triumphs can only come out of great trials.”

On Doubt

“The blood of Jesus Christ and His mighty name are an antidote to all the subtle seeds of unbelief that Satan would sow in your minds.”

On the Bigness of God

“There is nothing small about our God, and when we understand God, we will find out that there ought not to be anything small about us. We must have an enlargement of our conception of God, then we will know that we have come to a place where all things are possible, for our God is an omnipotent God for impossible positions.”

On the Renewing of Our Minds

“God wants to purify our minds until we can bear all things, believe all things, hope all things and endure all things. God dwells in you, but you cannot have this divine power until you live and walk in the Holy Ghost, until the power of the new life is greater than the old life.”

On an Eternal Perspective

“Never listen to human plans. God can work mightily when you persist in believing Him in spite of discouragement from the human standpoint … I am moved by what I believe. I know this: no man looks at the circumstances if he believes.”

On Spiritual Hunger

“The secret of spiritual success is a hunger that persists … It is an awful condition to be satisfied with one’s spiritual attainments … God was and is looking for hungry, thirsty people.”

On Reading Scripture

“It is as we feed on the Word and meditate on the message it contains that the Spirit of God can vitalize that which we have received, and bring forth through us the word of knowledge that will be as full of power and life as when He, the Spirit of God, moved upon holy men of old and gave them these inspired Scriptures.”

On Waiting on God

“These times of waiting on God for the fullness of the Spirit are times when He searches the heart and tests the mind.”

On Readiness

It is better to live ready than to get ready!”

On Complaining

“One half of the trouble in the assemblies is the people’s murmuring over the conditions they are in. The Bible teaches us not to murmur. If you reach that standard, you will never murmur anymore. You will be above murmuring. You will be in the place where God is absolutely the exchanger of thought, the exchanger of actions and the exchanger of your inward purity. He will be purifying you all the time and lifting you higher, and you will know you are not of this world.”

On God’s Strength

“You must come to see how wonderful you are in God and how helpless you are in yourself.”
