Bitter Honey?

"If you love me, you will keep my commandments. And I will ask the Father and He will give you another Helper to be with you forever, even the Spirit of truth whom the world cannot receive because it neither sees Him nor knows Him. You know Him for He dwells with you and will be with you." John 14:15-17

In commenting on this passage, Spurgeon writes:

So the worldlings say there is no Holy Ghost, because he cannot see it. Well, but we feel it. You say that is fanaticism, and that we never felt it. Suppose you tell me that honey is bitter, I reply 'No, I am sure you cannot have tasted it; taste it and try.' So with the Holy Ghost; if you did but feel his influence, you would no longer say there is no Holy Spirit, because you cannot see it."
