When asked if Scripture justifies the use of public invitations (altar calls) or not, Dr. Martyn Lloyd-Jones responded quite directly.
“The invitation should be in the message. We believe the Spirit applies the message, so we trust in the power of the Spirit….
…I feel that this pressure which is put upon people to come forward in decision ultimately is due to a lack of faith in the work and operation of the Holy Spirit. We are to preach the Word, and if we do it properly, there will be a call to a decision that comes in the message, and then we leave it to the Spirit to act upon people. And of course He does. Some may come immediately at the close of the service to see the minister. I think there should always be an indication that the minister will be glad to see anybody who wants to put questions to him or wants further help. But that is a very different thing from putting pressure upon people to come forward. I feel it is wrong to put pressure directly on the will. The order in Scripture seems to be this – the truth is presented to the mind, which moves the heart, and that in turn moves the will.”
