The faith of the natural man, the unregenerate man, may be reason able, logical and often very influential in his life (Matthew 7:21-23), but the faith of the Christian, true faith, is a miracle, and always produces a radical change in those who possess it (II Corinthians 5:1-17). It is a gift of God. (Ephesians; 2:8,9).

A man cannot possibly possess this saving faith, whose thinking and attitude has not been radically changed concerning God and righteousness, man and sin, and Christ and grace. The difference between the two kinds of faith, natural and spiritual, biblical and spurious, is the difference between shadows and substance, words and reality. Natural faith believes, but saving faith knows. Natural faith merely acknowledges what saving faith experiences. The difference is great. The difference is life or death. Therefore the great apostle to the Gentiles says to every professor, "Examine yourselves, whether ye be In the faith (the true faith); prove your own selves. Know ye not your own selves, how that Jesus Christ is in you, except ye be reprobates." (II Corinthians 13:5).
