A profession of faith and the possession of truth in the soul are two different things. The mere knowledge of truth is not enough. We may possess this, but the tenor of our thoughts may not be changed. The heart must be converted and sanctified.
The man who attempts to keep the commandments of God from a sense of obligation merely–because he is required to do so–will never enter into the joy of obedience. He does not obey. When the requirements of God are accounted a burden because they cut across human inclination, we may know that the life is not a Christian life. True obedience is the outworking of a principle within. It springs from the love of righteousness, the love of the law of God. The essence of all righteousness
is loyalty to our Redeemer. This will lead us to do right because it is right–because right doing is pleasing to God.
The great truth of the conversion of the heart by the Holy Spirit is presented in Christ’s words to Nicodemus: “Verily, verily, I say unto thee, Except a man be born from above, he can not see the kingdom of God. . . . That which is born of the flesh is flesh, and that which is born of the Spirit is spirit. Marvel not that I said unto thee, Ye must be born again. The wind bloweth where it listeth, and thou hearest the sound thereof, but canst not tell whence it cometh and whither it goeth. So is every one that is born of the Spirit.” John 3:3-8, margin.
