He [is in] the way of life
Of eternal life, which is truly, properly, and by way of eminency, "life", ( Matthew 19:17 ) ; and which is a life of glory; a life of perfection, of perfect holiness, knowledge, obedience, love, peace, and joy; a life free from all the inconveniences of the present life, animal or spiritual; a life of pleasure, and which will last for ever: the "way" to it is not by works of righteousness done by men, since by these the law is not fulfilled, nor justice satisfied; and therefore no justification of life by them, or what entitles to eternal life; it is sinful, dangerous, and a vain thing, to seek for eternal life in this way; Christ is the only true way to it; who, by his obedience, sufferings, and death, has opened the new and living way; and through his blood, righteousness, and sacrifice, way is made for all that believe in him to enter into eternal life: and such are in the way to it who are in Christ, secretly in election, openly in the effectual calling; when they are made new creatures, are quickened by the Spirit and grace of Christ, and have that principle in them which is a well of living water, springing up unto everlasting life; who have a sight of Christ, and come unto him by faith; who truly believe in him, with which eternal life is connected. Particularly he is in the way unto it that keepeth instruction;
the instruction in righteousness which the Scriptures give, especially the Gospel part of them; which is an instruction into the mind and will of God about man's salvation; into the grace of God, as displayed therein; into the person and offices of Christ, and salvation by him; into the doctrines of peace, pardon, righteousness, and life, through him. Now he to whom this instruction comes with power, and is the savour of life unto life; who receives it in the love of it; who "observes" F9 it, as the word here used signifies; takes notice of and follows its direction, pointing out Christ as the way of salvation, instructing to look to him and believe in him, and be saved; and who retains and holds fast such instruction, and abides by it; and finds the word of the Gospel, and eats it, and is nourished by it unto everlasting life; he is most assuredly in the way of it; but he that refuseth reproof erreth;
that is, from the way of life. He that rejects the counsel and advice, the admonitions and reproofs, given in the word of God, by the ministers of it; or by parents and masters, friends or relations, that wish him well; he wanders far off from the way that leads to life, and goes into the paths of sin, and consequently is in the way of death. Some render it, "causeth to err" {k}; either others, as Aben Ezra; or both himself and others, as Jarchi: and then it may be understood of him "that forsaketh reproof" {l}, as it may be rendered; that is, that declines giving reproof, when it lies in his way, and is his duty to do it. Aben Ezra reads this clause in connection with the former, as said of one and the same person,
``he is in the way of life that keepeth instruction, and forsakes or rejects the reproof of him that causeth to err.''
