"WHOSOEVER goeth onward and abideth not in the teaching of Christ, hath not God: he that abideth in the teaching, the same hath both the Father and the Son." 2 John 9. "I and My Father are one," the Saviour expressly declares, — one in power, in love, in purpose; Their law and will are one. That which is of the Father is also of the Son. The creation of the world was through the Son, the Word. The work of redemption was the work of the Father through the Son; He gave His only-begotten Son. God's will is expressed in His law, the words of which were spoken by the Son, fulfilled by the Son, commanded by the Son for His followers.
There is only one way by which man may have the Father in his life — by obedience to Him. There is only one standard of obedience — God's law. The "teaching of Christ" brings God into man's life. Therefore, the law of God and the teaching of Christ are identical. "He that abideth in the teaching, the same hath both the Father and the Son."
Here is the testimony of the beloved disciple. He who told only "that which we have heard, that which we have seen with our eyes, that which we beheld, and our hands handled, concerning the Word of life," — makes not so much as a mention of a change in the law of God. Instead, he says: "Whatsoever we ask we receive of Him [of God], because we keep His commandments and do the things that are pleasing in His sight."
