In the Bible we have the unerring counsel of God. Its teachings, practically carried out, will fit men for any position of duty. It is the voice of God speaking every day to the soul.... The work of the Holy Spirit is to enlighten the darkened understanding, to melt the selfish, stony heart, to subdue the rebellious transgressor, and save him from the corrupting influences of the world. The prayer of Christ for His disciples was, “Sanctify them through Thy truth; Thy word is truth.” John 17:17L. The sword of the Spirit, which is the word of God, pierces the heart of the sinner, and cuts it in pieces. When the theory of the truth is repeated without its sacred influence being felt upon the soul of the speaker, it has no force upon the hearers, but is rejected as error, the speaker making himself responsible for the loss of souls.—Testimonies for the Church 4:441.
