Spurgeon's evangelistic stratergy

Apparently CHS said:

To try to win a soul for Christ by keeping that soul in ignorance of any truth, is contrary to the mind of the Spirit; and to endeavor to save men by mere claptrap, or excitement, or oratorical display, is as foolish as to hope to hold an angel with bird-lime, or lure a star with music. The best attraction is the gospel in its purity. The weapon with which the Lord conquers men is the truth as it is in Jesus. The gospel will be found equal to every emergency; an arrow which can pierce the hardest heart, a balm which will heal the deadliest wound. Preach it, and preach nothing else.
