especially when one considers the presentation of the gospel is grounded in the doctrines of grace.
I believe that, too. And any invitation, altar call, exhortation should be consistent with that gospel. That means that the very language we use in calling men and women to repentance and faith is critical. There must be no uncertain trumpet.
So coming forward,walking the aisle, coming to Christ, accepting Christ, are expressions that must not be used as buzzwords, without explaining to listeners what they mean and what they don't mean. It is a dangerous thing to have a lost person to hear that salvation is available down there where the preacher is.
Another uncertain trumpet can be the so-called "Sinner's Prayer." Now it is perfectly legitimate for a sinner to ask God to save him. But it is perfectly horrible to suggest that those "magic words" are all that's necessary.
Have you ever heard someone say
"Okay pray this prayer. Just say....."
"Did you pray that prayer?"
"Did you really, really, really, really mean it?"
"Yes? Then I declare you to be a child of God."
One may think I'm making too big a deal out of all this. You'll change your mind when you hear somebody tell you their sole hope of heaven is "well, I said the prayer." No repentance, no mention of faith, no commitment to follow Christ's commands. Just saying the words.
To be sure, one may ask God for salvation out of a repentant and trusting heart. But our job is to blow a certain, clear trumpet.
