Introduction
There are many matters concerning which total ignorance and complete indifference are neither tragic nor fatal. I believe many of you are probably totally ignorant of Einstein’s theory of relativity, and if you were pressed to explain it to someone you would really be in difficulty. Not only are you ignorant of Einstein’s theory of relativity, you are probably quite indifferent, and that ignorance and indifference is neither fatal nor tragic.
I am sure there are few of us who can explain all the processes by which a brown cow eats green grass and gives white milk. It does not keep you from enjoying the milk. But there are some things concerning which ignorance and indifference are both tragic and fatal, and one such thing is the Bible’s answer to the question I am about to set before you.

‘What is a biblical Christian?’ In other words, when does a man or woman, a boy or girl, have the right to take to himself or herself the name Christian, according to the Scriptures?
We do not want to make the assumption lightly that you are true Christians. I want to set before you four strands of the Bible’s answer to that question.
According To The Bible, A Christian Is A person Who Has Faced Realistically The Problem Of His Own Personal Sin
Now one of the many unique things about the Christian faith is this — unlike most of the religions of the world, Christianity is essentially and fundamentally a sinner’s religion. When the angel announced to Joseph the approaching birth of Jesus Christ, he did so in these words, ‘Thou shalt call his name Jesus, for he shall save his people from their sins’ [Matt 1.21]. The apostle Paul wrote in I Timothy 1.15, ‘This is a faithful saying and worthy of all acceptance, that Christ Jesus came into the world to save sinners’. He came into the world to save sinners. The Lord Jesus Christ himself says in Luke 5.31-32, ‘Those that are healthy do not need a doctor but those who are sick. I did not come to call the righteous, but sinners to repentance’. And the Christian is one who has faced realistically this problem of his own personal sin.

When we turn to the Scripture and seek to take in the whole of its teaching on the subject of sin, right down to its irreducible minimum, we find that the Scripture tells us that each one of us has a two-fold personal problem in relation to sin. On the one hand, we have the problem of a bad record and, on the other, the problem of a bad heart. If we start in Genesis 3 and read that tragic account of man’s rebellion against God and his fall into sin, then trace the biblical doctrine of sin all the way through the Old Testament, and on into the New, right through to the Book of Revelation, we shall see that it is not over-simplification to say that everything that the Bible teaches about the doctrine of sin can be reduced to those two fundamental categories – the problem of a bad record and the problem of a bad heart.
What do I mean by ‘the problem of a bad record’? I am using that terminology to describe what the Scripture sets before us as the doctrine of human guilt because of sin. The Scripture tells us plainly that we obtained a bad record long before we had any personal existence here upon the earth: ‘Wherefore, as by one man sin entered into the world, and death by sin, and so death passed upon all men, for that all have sinned’ [Rom 5.12]. When did the ‘all’ sin? We all sinned in Adam. He was appointed by God to represent all of the human race and when he sinned we sinned in him and fell with him in his first transgression. That is why the apostle writes in 1 Corinthians 15.22, ‘As in Adam all die’. We passed our age of accountability in the Garden of Eden and from the moment Adam sinned we were charged with guilt. We fell in him in his first transgression and we are part of the race that is under condemnation.

Furthermore, the Scripture says, after we come into being at our own conception and subsequent birth additional guilt accrues to us for our own personal, individual transgressions. The Word of God teaches that there is not a just man upon the face of the earth who does good and does not sin [Eccles 7.20], and every single sin incurs additional guilt. Our record in heaven is a marred record. Almighty God measures the totality of our human experience from the moment of our birth by a standard which is absolutely inflexible; a standard that touches not only our external deeds but also our thoughts and the very motions and intentions of our heart; so much so, that the Lord Jesus said that the stirring of unjust anger is the very essence of murder, the look with intention to lust as adultery.
And God is keeping ‘a detailed record’. That record is among ‘the books’ which will be opened in the Day of Judgment [Rev 20.12]. And there in those books is recorded every thought, every motive, every intention, every deed, every dimension of human experience that is contrary to the standard of God’s holy law, either failing to measure up to its standard or transgressing it. We have the problem of a bad record – a record in which we are charged with guilt; real guilt for real sin committed against the true and the living God. That is why the Scripture tells us that the entire human race stands guilty before Almighty God [Rom 3.19].

Has the problem of your own bad record ever become a burning, pressing personal concern to you? Have you faced the truth that Almighty God judged you guilty when our first father sinned, and holds you guilty for every single word you have spoken contrary to perfect holiness and justice and purity and righteousness? He knows every object you have touched and taken contrary to the sanctity of property and every word spoken contrary to perfect, absolute truth. Has this ever broken in upon you, so that you awakened to the fact that Almighty God has every right to summon you into his presence and to require you to give an account of every single deed contrary to His law, which has brought guilt upon your soul?
Certainly we have the problem of a bad record but we have an additional problem – the problem of a bad heart. We not only are pronounced guilty in the court of heaven for what we have done. The Scripture teaches that the problem of our sin is one that arises not only from what we have done, but from what we are. When Adam sinned he not only became guilty before God, but defiled and polluted in his own nature. The Scripture describes it in Jeremiah 17.9, ‘The heart is deceitful above all things and desperately wicked; who can know it?’ Jesus describes it in Mark 7.21, ‘From within, out of the heart of man, proceed…’and then He names all the various sins that can be seen in any newspaper on any day — blasphemies, pride, adulteries, murder.
Jesus said that these things rise out of this artesian well of pollution, the human heart. Notice carefully that he did not say, ‘For from without, by the pressure of society and its negative influences, come forth murder and adultery and pride and thievery’. That is what our so called sociological experts tell us. It is ‘the condition of society’ that produces crime and rebellion. Jesus says it is the condition of the human heart. For from within, out of the heart, proceed these things — lies, selfishness, self-centredness, total preoccupation with my feelings and my desires and my plans and my perspectives.
We have hearts that the Scripture describes as ‘desperately wicked’ – the fountain of all forms of iniquity. To change the biblical imagery, Romans 8.7 reads, ‘The carnal mind is enmity against God, for it is not subject to the law of God, neither indeed can it be’. Paul says that the carnal mind, that is, the mind that has never been regenerated by God, is not reflective of some enmity; he calls it enmity itself. ‘The carnal mind is enmity against God’. The disposition of every human heart by nature can be visually pictured as a clenched fist raised against the living God. This is the inward problem of a bad heart – a heart that loves sin, a heart that is the fountain of sin, a heart that is at enmity with God. And such is the problem that every one of us has by nature.

Has the problem of your bad heart ever become a pressing personal concern to you? I am not asking whether you believe in human sinfulness in theory. Oh, there is such a thing as a sinful nature and a sinful heart. My question is: Have your bad record and your bad heart ever become a matter of deep, inward, personal, pressing concern to you? Have you known anything of real, personal, inward consciousness of the awfulness of your guilt in the presence of a holy God? – the horribleness of a heart that is ‘deceitful above all things and desperately wicked’?
A Bible Christian is a person who has in all seriousness taken to heart his own personal problem of sin.
Now the degree to which we may feel the awful weight of sin differs from one person to another. The length of time over which a person is brought to the consciousness of his bad record and his bad heart differs. There are many variables, but Jesus Christ as the Great Physician never brought his healing virtue to any who did not know themselves to be sinners. He said, ‘I did not come to call the righteous, but sinners to repentance’ [Matt 9.13]. Are you a Bible Christian, one who has taken seriously your personal problem of sin?
