They preach because they love me, for they know the Lord brought me here to defend the Good News.
Philippians 1:16

I think you will agree that today there are many Christians who are firmly convinced that answering the intellectual questions of unbelievers is an ineffectual waste of time. They feel that any involvement of the mind in the gospel interchange smacks too much of human effort and really just dilutes the Spirit's work.

But Christianity thrives on intelligence, not ignorance. If a real Reformation is to accompany the revival for which many of us pray, it must be something of the mind as well as the heart. It was Jesus who said, "Come and see." He invites our scrutiny and investigation both before and after conversion.

We are to love God with the mind as well as the heart and the soul. In fact, the early church was powerful and successful because it out-thought and out-loved the ancient world. We are not doing either very well today. Most Christians today seem to prefer experiencing Christianity to thinking about or explaining it. But consider these verses:

Matthew 13:23: "But he who received the seed on the good ground is he who hears the word and understands it, who indeed bears fruit." They all heard it, but only the "good soil" comprehended it.

Acts 8:30: "When the Spirit prompted Philip to join himself to the chariot of the Ethiopian eunuch (who was reading Isaiah 53), he asked, `Do you understand what you are reading?' The eunuch replied, `How can I except some man should guide me?'"

Acts 18:4: Paul at Corinth was "reasoning in the synagogue every sabbath and trying to persuade the Jews and Greeks."

Acts 19:8: Paul at Ephesus "entered the synagogue and continued speaking out boldly for three months, reasoning and persuading them about the kingdom of God."

Romans 10:17: "So then faith comes by hearing and hearing by the word of God." Again the emphasis is on hearing with perception.

2 Corinthians 5:11: "We persuade men," says Paul. Vine's Expository Dictionary describes this Greek word like this: "to apply persuasion, to prevail upon or win over, bringing about a change of mind by the influence of reason or moral considerations."

All of these words--persuasion, dialogue, discourse, dispute, argue, present evidence, reason with--are vehicles of communication and are at the heart of Paul's classical evangelistic model. Can there be saving faith without understanding? Can there be understanding without reasoning? The Bible would appear to say no. Paul urges believers in 2 Timothy 2:15 to study to show ourselves approved unto God, workmen that need not to be ashamed.

J. Gresham Machen, a great Christian scholar, said the following words in 1912 to a group of young men at Princeton Seminary:

It would be a great mistake to suppose that all men are equally well-prepared to receive the gospel. It is true that the decisive thing is the regenerative power in connection with certain prior conditions for the reception of the Gospel. . . . I do not mean that the removal of intellectual objections will make a man a Christian. No conversion was ever wrought by argument. A change of heart is also necessary . . . but because the intellectual labor is insufficient, it does not follow that it is unnecessary. God may, it is true, overcome all intellectual obstacles by an immediate exercise of His regenerative power. Sometimes He does. But He does so very seldom. Usually He exerts His power in connections with certain conditions of the human mind. Usually He does not bring into the kingdom, entirely without preparation, those whose mind and fancy are completely contaminated by ideas which make the acceptance of the Gospel logically impossible.

If these words were true in 1912, how much more are they needed today?
