II. THE IMPERATIVE NECESSITY OF THE NEW BIRTH.
1. THE NECESSITY IS UNIVERSAL.
The need is as far reaching as sin and the human race: "Except a man (lit. anybody) be born again, he cannot see the kingdom of God" (John 3:3, cf. v. 5). No age, sex, position, condition exempts anyone from this necessity. Not to be born again is to be lost. There is no substitute for the new birth: "Neither circumcision availeth anything, nor uncircumcision, but a new creature" (Gal. 6:15). The absolute necessity is clearly stated by our Lord: whatever is born of the flesh, must be born again of the Spirit (John 3:3-7).
2. THE SINFUL CONDITION OF MAN DEMANDS IT.
John 3:6—"That which is born of the flesh is flesh"—and it can never, by any human process, become anything else. "Can the Ethiopian change his skin, or the leopard his spots? then may ye also do good that are accustomed to do evil" (Jer. 13:23). "They that are in the flesh cannot please God" (Rom. 8:8); in our "flesh dwelleth no good thing" (Rom. 7:18). The mind is darkened so that we cannot apprehend spiritual truth; we need a renewing of the mind (Rom. 12:2). The heart is deceitful, and does not welcome God; we need to be pure in heart to see God. There is no thought of God before the eyes of the natural man; we need a change in nature that we may be counted among those "who thought upon His name." No education or culture can bring about such a needed change. God alone can do it.
3. THE HOLINESS OF GOD DEMANDS IT.
If without holiness no man shall see the Lord (Heb. 12:14); and if holiness is not to be attained by any natural development or self-effort, then the regeneration of our nature is absolutely necessary. This change, which enables us to be holy, takes place when we are born again.
Man is conscious that he does not have this holiness by nature; he is conscious, too, that he must have it in order to appear before God (Ezra 9:15). The Scriptures corroborate this consciousness in man, and, still further, state the necessity of such a righteousness with which to appear before God. In the new birth alone is the beginning of such a life to be found. To live the life of God we must have the nature of God.
