“You may talk about power; but, if you neglect the one Book that God has given you as the one instrument through which He imparts and exercises His power, you will not have it. You may read many books and go to many conventions and you may have your all-night prayer meetings to pray for the power of the Holy Ghost; but unless you keep in constant and close association with the one Book, the Bible, you will not have power.

“And if you ever had power, you will not maintain it except by the daily, earnest, intense study of that Book. Ninety-nine Christians in every hundred are merely playing at Bible study; and therefore ninety-nine Christians in every hundred are mere weaklings, when they might be giants, both in their Christian life and in their service.”  —R. A. Torrey
