Zechariah 9:12 "Turn you to the strong hold, ye prisoners of hope: even to day do I declare that I will render double unto thee;"
Isaiah 11:6 "and a little child shall lead them."
I have always been struck by the call to simplicity and hope when it comes to reaching others with the gospel. In studying revival I have also read of how artificially-created sensational approaches, often bring short-term results—things that are sensational get attention and people are really "wowed" by what they are hearing, but also bring about emotion-based responses that are short-lived and sometimes not positive, instead of conscience-based responses that are the result of the convicting work of the Holy Spirit. By way of example, Charles Finney, the eminent revivalist who worked in the Northeastern part of the united States in the 1800s specifically cautioned against emotion-based revival. The following quotation from the pen of Ellen White gives direction along the line of simplicity and hope:
"Those who have the out pouring of the gospel of Christ which comes from the heart imbued by His Holy Spirit will give light and comfort and hope to hearts that are hungering and thirsting for righteousness. It is not excitement we wish to create, but deep, earnest consideration, that those who hear shall do solid work, real, sound, genuine work that will be enduring as eternity. We hunger not for excitement, for the sensational; the less we have of this, the better. The calm, earnest reasoning from the scriptures is precious and fruitful. Here is the secret of success, in preaching a living, personal Saviour in so simple and earnest a manner that the people may be able to lay hold by faith of the power of the word of life. [Preach] ... the truth, substantiated by the authority of the living word, which is the power of God unto salvation. Ellen G. White, Paulson Collection, 101.3
