Seeing as Spurgeon has been quoted, I thought I'd share a couple more of his gems.
How does God speak to us then, and how does He expect us to answer? He speaks to us in the written Word. This “more sure Word of testimony, whereunto you do well if you take heed, as unto a light that shines in a dark place.” He speaks to us also in the ministry of His Word, when things new and old which are in Holy Scripture are brought forth by His chosen servants and are applied with power to our hearts by the Holy Spirit.
The Lord is not dumb in the midst of His family, though, alas, some of His children appear to be dull of hearing. Though the Urim and Thummim are no longer to be seen upon the breasts of mortal men, yet the oracle is not silent. O that we were always ready to hear the loving voice of the Lord.

“But how does the Lord speak?” someone asks. That is a very important question. I know that He has many ways of speaking to the hearts of His people. We do not expect to hear audible words. It is not by sense that we live—not even by the sense of hearing—but by faith. We believe and so we apprehend God.
God often speaks to His children through His works. Are there not days when the mountains and the hills break forth before us into singing and the trees of the field clap their hands because God is speaking by them? Do you not lift up your eyes to the heavens at night and watch the stars and seem to hear God speaking to you in the solemn silence? That man who never hears God speak through His works is, I think, hardly in a healthy state of mind. Why, the very beauty of spring with its promise, the fullness of summer, the ripeness of autumn and even the chilly blasts of winter are all vocal if we have but ears to hear what they say!
God also speaks to His children very loudly by His Providence. Is there no voice in affliction? Has pain no tongue? Has the bed of languishing no eloquence? The Lord speaks to us, sometimes, by bereavement—when one after another has been taken away, God has spoken to us. The deaths of others are for our spiritual life—sharp medicine for our soul’s health. God has spoken to many a mother by the dear babe she has had to lay in the grave. And many a man has, for the first time, listened to God’s voice when he has heard the passing bell that spoke of the departure of one dearer to him than life itself. God speaks to us, if we will but hear, in all the arrangements of Providence both pleasant and painful. Whether He caresses or chastises, there is a voice in all that He does. Oh, that we were not so deaf!
But the Lord speaks to us chiefly through His Word. Oh, what converse God has with His people when they are quietly reading their Bibles! There, in your still room, as you have been reading a chapter, have you not felt as if God spoke those words straight to your heart then and there? Has not Christ Himself said to you, while you have been reading His Word, “Let not your heart be troubled: you believe in God, believe also in Me”? The text does not seem to be like an old letter in a book, rather is it like a fresh speech, newly spoken from the mouth of the Lord to you. It has been so, dear Friends, has it not?

There are certain fanatics who get delirious and dream that they are prophets, and I know not what. But we just put them to the side. This is a very different thing from being guided by the Spirit of God in all the actions of life so as to obey the will of the Lord, sometimes, in cases where we might not have known it to be His will, or might have omitted it.
