I came across this on the Puritan Fellowship Blog. Good stuff I might add.
"Another thing that we must deal with and you must deal with is the Gospel call. Of faith. Of repentance. Jesus did not come to Israel saying "the time is fulfilled, the Kingdom of God is at hand, now who wants to ask me into their heart?" He cried out "Repent and believe". But now let me tell you something: You need to be balanced. Because I know a lot of guys who are reformed who if they make any sought of Gospel call at all they're always quick to say "Now in making that call I also know that if God doesn't move on your heat you can't come." Stop it! Don't do that! You get up there and you plead for men to repent! You plead for men to believe! And don't try to defend yourselves just in case there are a few hyper-Calvinists that have a problem with an open invitation in the audience. If you're always doing something like that and then explaining yourself you've got a problem with pride and what men think about you. That's why I love Spurgeon so much. He was true in his Gospel. He cried out for men to be saved. Don't be passive: "well I've laid the Gospel for them, I've laid it out, let's just all sit here". You're preaching to dying men. Don't manipulate them. But I'm not manipulating a man when I see him running in front of a train and I scream out: "stop!" I'm reacting to the severity of the situation. I want you not to trust ever in the arm of the flesh. I want you to isolate yourself to this one thing: unless God moves nothing is going to happen. But I want you to do what Scripture does and that is cry out to men. Beg me. You leave men saying "I have to leave you now, please hear my voice, I'm begging you. Listen to the Gospel." Be passionate preachers."~Paul Washer
