From the pen of Charles H. Spurgeon:
Happy is the nation which is blessed with the means of grace. No man was ever saved by the means of grace apart from the Holy Spirit. You may hear the sermons of the man whom God delights to honor; you may select from all your divines the writings of the man whom God did bless with a double portion of his Holy Spirit; you may attend every meeting for prayer; you may turn over the pages of his blessed book; but in all this, there is no life for the soul apart from the breath of the Divine Spirit. Use these means, we exhort you to use them, and use them diligently; but remember that in none of these means is there anything that can benefit you unless God the Holy Spirit shall own and crown them. These are like the conduit pipes of the market place; when the fountain-head flows with the water then they are full, and we do derive a blessing from them; but if the stream is held back, if the fountain head does cease to give forth its current, then these are wells without water, clouds without rain; and you may go to ordinances as an Arab turns to his skin bottle when it is dry, and with your parched lips you may suck the wind and drink the whirlwind, but receive neither comfort, nor blessing, nor instruction, from the means of grace.
