A Christian: Keeps the Faith of Jesus Christ

Revelation 14:12 What is a Christian?

Drawing on Revelation 14:12, Martin expounds the second of two defining marks of a Christian: keeping 'the faith of Jesus,' which he establishes means not merely subjective trust in Christ but the entire body of revealed truth that centers on his person and work. He traces why this mark belongs to every true believer -- because the faith of Jesus is the very instrument through which God imparted new life, and no one can abandon what gave them life. The sermon then applies three searching tests: willful ignorance of the faith of Jesus, bland indifference to it, and unwillingness to bear reproach for it are each shown to be evidence of an unregenerate heart. Martin closes by calling believers to doctrinal vigilance for the sake of unborn generations, warning that lines blurred in one generation become lines obscured in the next.

Airline Pilot Analogy

In this part of the sermon: Martin recaps the morning sermon's question -- 'what is a Christian?' -- and locates the evening's focus in Revelation 14:12, which defines the saints by two marks: keeping the…

Martin distinguishes 'what is a Christian?' from 'how does one become a Christian?' using the parallel: defining what an airline pilot is (one who sits behind the controls directing the aircraft) is different from explaining how to become one. The two questions require different answers.

Now that question is not the same as how does one become a Christian. And I used this morning the simple illustration of the question, what is an airline pilot? It's someone who sits behind the controls of an airliner and directs the activities of that complex machine. Now if you ask the question, how to become an airline pilot, that's a much more involved answer.

Pilgrims on the Way to the Celestial City

Using Bunyan's Pilgrim's Progress language, Martin frames the question as 'how can you know a true pilgrim when you see him there upon the way to the celestial city?' -- shifting from the question of entry to the question of identification.

It's a different issue. So we are not addressing ourselves to the question, how does one become a Christian? How does one enter into the narrow gate, to use Bunyan's analogy? But rather we're asking the question, how can you know a true pilgrim when you see him?

Bunyan's Ignorance: The Deceitful Heart

The point: A person who claims to be a Christian solely because their heart tells them so -- without the testimony of Scripture confirming it -- has a deceitful heart that cannot be trusted. Assurance must be grounded in the word o…

Martin quotes from Pilgrim's Progress the exchange with the character Ignorance, who claims to be a Christian because his heart tells him so. The reply: 'If thy heart agree not to the word of God, it is a deceitful heart, and it is not to be trusted.' Applied as the danger of assurance grounded in feeling rather than Scripture.

For Jesus said, My yoke is easy and my burden is light. And if this is not the characteristic of our life, a course of obedience described in these biblical concepts, then we are committing spiritual suicide to say that we are Christians simply because, like that man Ignorance in Bunyan's allegory, our heart tells us so. For as they answered him, If thy heart agree not to the word of God, it is a deceitful heart, and it is not to be trusted. Now tonight, we come to the second characteristic of a Christian.

Martin's wife told him that afternoon that he almost got to preaching three-quarters of the way through the morning sermon when he started applying the truth about no man's land -- the rest of the time he was merely teaching. Martin uses this as an occasion to explain and defend his expository method.

Now, I hope this isn't tedious for you. I, once in a while, get sort of chided by my wife. She'll say to me, as she did this afternoon, she said, you know, dear, you almost got to preaching about three-quarters of the way through the sermon this morning when you started talking about having no area of no man's land that you've reserved. The rest of the time you were teaching.

Gathering Clouds Before the Storm

Martin defends his careful word-study method: 'I have no grounds to preach up a stage, storm three-quarters of the way through unless I've gathered some clouds of truth so that there's some real water in the storm in the first two-thirds of the sermon.' Expository teaching provides the substance that makes application powerful.

And I said, dear, I don't know any other way to preach. I have no grounds to preach up a stage. Storm three-quarters of the way through unless I've gathered some clouds of truth so that there's some real water in the storm in the first two-thirds of the sermon. And I hope this never becomes tedious for us.

What Is 'The Faith of Jesus'? Two Senses in Scripture

Paul's Dying Declaration: 'I Have Kept the Faith'

Driving home: It is called the faith of Jesus because He is its author and He is the grand object and He is the focal point of that entire body, of truth.

Martin quotes 2 Timothy 4:7 and unpacks it as Paul saying on the threshold of martyrdom that he clung to the body of revealed truth, did not pare off its rough edges, did not whittle it down for unregenerate nature, and did not adorn it with human rhetoric.

things that were contrary to the body of revealed truth. So, the term the faith here obviously means the body of revealed truth. In 2 Timothy 4, 7, the apostle about to go into the presence of his God by way of the gate of martyrdom says, I have fought a good fight. I have kept the faith.

The Church at Pergamos: Martyrdom Rather Than Denial

Driving home: It is called the faith of Jesus because He is its author and He is the grand object and He is the focal point of that entire body, of truth.

The church at Pergamos dwelt where Satan's throne was; when the issue came whether to confess or deny the body of revealed truth, they chose martyrdom over forfeiting one aspect of the word of God. Antipas was killed among them and they still did not deny the faith.

Revelation 2 and verse 13, writing to the church of Pergamos, I know where thou dwellest, even where Satan's throne is, and thou holdest fast my name and didst not deny my faith, even in the days of Antipas my witness, my faithful one who was killed among you where Satan dwelleth. When the issue came whether or not men would confess their commitment to the body of revealed truth, they did not deny any aspect of that truth, but rather chose martyrdom than to forfeit one aspect of the word of the living God.

Lloyd-Jones at Carlisle: A Man Whose Mouth Has Been Shut

Driving home: Has your mouth ever been shut? Until you've been brought speech before a holy God in the face of your own sin. That's a Christian, a man whose mouth has been stopped.

At a conference in Carlisle, Dr. Martyn Lloyd-Jones preached on Romans 3:19, defining a Christian as 'a man whose mouth has been shut' -- speechless before a holy God in the face of his own sin. Martin recalls Lloyd-Jones saying it 'with his growly, gravelly, Welsh voice.' Cited as the essential first movement in conversion.

When we were at Carlisle in the conference, the tapes of which, by the way, are now in our tape library available for loaning, I guess as soon as our tape deacon can get some copies made, Dr. Lloyd-Jones, one night preaching on Romans 3 and the principle that I'm touching here now said the good definition of a Christian is a man whose mouth has been shut. And he said it with his growly, gravelly, Welsh voice. And he took it from Romans 3.19.

The Blessed Message Coming Through Different Means

Driving home: Has your mouth ever been shut? Until you've been brought speech before a holy God in the face of your own sin. That's a Christian, a man whose mouth has been stopped.

To the person whose mouth has been stopped by the law, 'a blessed message has come. It has come through perhaps different means, by way of a book, by way of a friend, by way of a sermon.' Martin narrates the three-part structure of conversion: hearing of the unique Person, the unique Work, the unique Offer.

How can he be just and still forgive a creature like me? And to that person, that Christian, who was a fallen son of Adam, having made that discovery, a blessed message has come. It has come through perhaps different means, by way of a book, by way of a friend, by way of a sermon. But this blessed message has come setting forth, first of all, a unique person who has undertaken to come to the aid of sinners who are facing that dilemma.

The Dilemma of the Substitute

Driving home: Has your mouth ever been shut? Until you've been brought speech before a holy God in the face of your own sin. That's a Christian, a man whose mouth has been stopped.

Martin presents the logical dilemma: a substitute must be human to die in place of man, but if he is merely another man he shares man's dilemma. 'He must be more than a man. And yet he must be a man.' This logical necessity drives toward the Incarnation as the only solution.

Death must be incurred. Either I must die in eternal death or there must be a substitute provided. But the substitute must be a man if he's to die. But if he's just another man, he's in the same dilemma with me.

'The guiltless becomes guilty before the law that the guilty might be guiltless.' Martin presents the double imputation of substitutionary atonement in a single compact formula before describing the free offer of mercy.

The guiltless becomes guilty before the law that the guilty might be guiltless. Then he has heard in the third place of the unique offer of mercy that has been made to him. This unique offer that without bringing any supposed human merit, without any long delay of penance and self-inflicted punishment, by renouncing all sin and self-righteousness and embracing this unique person who accomplished this unique work, forgiveness and pardon are secured. They are secured.
