John Darby’s Synopsis
 Compare, for this substitution of Christ for Israel, Isaiah 49. He began Israel over again in blessing, as He did man.
 There are the three exhortations: Abide in me; If ye abide in Me and My words abide in you ye shall ask what ye will; Abide in My love.
 Some have thought that this means the joy of Christ in the faithful walk of a disciple: I do not think so. It is the joy He had down here, just as He left us His own peace, and will give us His own glory.
 He does not say "loveth me," but "hath loved me"; that is, He does not speak merely of the eternal love of the Father for the Son, but of the Father's love displayed towards Him in His humanity here on earth.
 By choosing them and setting them apart to enjoy together this relationship with Him outside the world, He had put them in a position of which mutual love was the natural consequence; and, in fact, the sense of this position and love go together.
 Remark, that His word and His works are here again referred to.
 Observe here the practical development, with respect to life, of this most deeply interesting subject, in 1 John 1 and 2. The eternal life which was with the Father had been manifested (for in Him, in the Son, was life, He was also the Word of life, and God was light. Compare John 1). They were to keep His commandments (chap. 2:3-5). It was an old commandment which they had had from the beginning-that is, from Jesus on earth, from Him whom their hands had handled. But now this commandment was true in Him and in them: that is to say, this life of love (of which these commandments were the expression) as well as that of righteousness reproduced itself in them, by virtue of their union with Him, through the Holy Ghost, according to John 14:20. They also abode in Jesus (1 John 2:6). In John 1 we find the Son who is in the bosom of the Father, who declares Him. He reveals Him as He has thus known Him-as that which the Father was to Himself. And He has brought this love (of which He was the object) down into the bosom of humanity, and placed it in the heart of His disciples (see chapter 17:26); and this is known now in perfection by God dwelling in us, and His love being perfect in us, while we dwell in brotherly love (1 John 4:12; compare John 1:18). The manifestation of our having been thus loved will consist in our appearing in the same glory as Christ (chap. 17:22, 23). Christ manifests this love by coming from the Father. His commandments teach it us; the life which we have in Him reproduces it. His precepts give form to this life, and guide it through the ways of the flesh, and the temptations in the midst of which He, without sin, lived by this life. The Holy Ghost is its strength, as being the mighty and living link with Him, and He by whom we are consciously in Him and He in us. (Union, as the body to the Head, is another thing, which is never the subject of John's teaching.) Of His fulness we receive grace upon grace. Therefore it is that we ought to walk as He walked (not to be what He was); for we ought not to walk in the flesh, although it is in us and was not in Him.
