Why 'Church'?

"Jesus answered them, "I told you, and you do not believe; the works that I do in My Father's name, these testify of Me. "But you do not believe because you are not of My sheep. "My sheep hear My voice, and I know them, and they follow Me; and I give eternal life to them, and they will never perish; and no one will snatch them out of My hand. My Father, who has given them to Me, is greater than all; and no one is able to snatch them out of the Father's hand. "I and the Father are one." -- John 10:25-30

"How, then, can they call on the one they have not believed in? And how can they believe in the one of whom they have not heard? And how can they hear without someone preaching to them? And how can they preach unless they are sent? As it is written, "How beautiful are the feet of those who bring good news!" -- Romans 10:14-16

'The Preaching of the Word by the chosen servants of the living God, is the ordained means for gathering in of the elect. It is not the Word read, so much as that which is heard, which has the promise attached to it; hence the importance of a devout attendance on the ministry of the Gospel' -- Charles Spurgeon
