Now the graces that have been mentioned, namely, justification, regeneration, adoption and the witness of the Spirit, are all received co-instantaneously. They always accompany each other, and whoever has one of them has them all. The witness of the Spirit, it is true, is not always a constant experience. It may be intermittent, but, nevertheless, whenever it is present, it accompanies or attends the other experiences to which we have alluded. And we may add that all these graces are but different aspects of the same salvation and are properly and conveniently designated, in common language, by the single term conversion, which term, therefore, must be understood to include and imply justification, regeneration, adoption and the witness of the Spirit. It is proper, also, in this connection to remark that conversion is always a definite and instantaneous event, and never a prolonged process. Just so certainly as every human being that comes into this world has a definite, natural birthday, so every one that comes into the kingdom of God has a definite, spiritual birthday. Some people do not know when their natural birthday occurs, nevertheless, they know that they have been born. Some Christians do not know when their spiritual birthday occurs. Nevertheless, they know that they have been born again. Conversion is the crossing of a definite line out of Satan's kingdom into God's kingdom. There is no half-way ground, there is no neutral territory, there is no place where a man can truthfully say, I am neither converted nor unconverted. One moment he is out of the ark of safety, the next moment he is in it. Entire sanctification is an act of God's grace by which inbred sin is removed and the heart made holy. Inbred sin or inherited depravity is the inward cause of which our outward sins are the effects. It is the bitter root of which actual sins are the bitter fruits. It is the natural evil tendency of the human heart in our fallen condition. It is the being of sin which lies back of the doing of sin. It is that within us which says No, to God, and Yes, to Satan. It exists in every human being that comes into the world as a bias or proclivity to evil. It is called in the New Testament, the flesh, the body of sin, our old man, sin that dwelleth in me, and the simple term sin in the singular number. In the Old Testament it is called sin and iniquity. "Behold," says David, "I was shapen in iniquity and in sin did my mother conceive me." And when the Seraph brought the live coal and laid it upon the mouth of Isaiah, the prophet, his words were, "Lo, this hath touched thy lips and thine iniquity is taken away and thy sin purged."
