One of my favorite quotes by the late preacher Matthew Simpson:
"His throne is the pulpit; he stands in Christ's stead; his message is the word of God; around him are immortal souls; the Saviour, unseen, is beside him; the Holy Spirit broods over the congregation; angels gaze upon the scene, and heaven and hell await the issue. What associations, and what vast responsibility! "
1 Tim 4:16 Take heed unto thyself, and unto the doctrine; continue in them: for in doing this thou shalt both save thyself, and them that hear thee.(KJV)
