“The life of a mature Christian is the life of the vicariously-lived life of Christ. The Lord Himself—through the Spirit, lives His life in us and is evident by the works of righteousness which He does using us.
“I live; yet not I, but Christ lives in me: and the life which I now live in the flesh (physical body) I live by the faith of the Son of God” (Gal 2:20). “By”, not on the faith of Christ. We live on and in Christ, by or through faith. We do not live on faith but by faith, because it’s Christ we live on.” -NC
“By the faith of the Son of God”: “not that faith which Christ, as man, had, but that of which He is the author and object, by which the just man lives; not upon it, for the believer does not live upon any of his graces, no, not upon faith, but by faith on Christ, the object; looking to Him for pardon, righteousness, peace, joy, comfort, every supply of grace, and eternal salvation: which object is described as "the Son of God"; who is truly God, equal with His Father; so that he did not live upon a creature, or forsake the fountain of living waters, but upon the only begotten Son of God, who is full of grace and truth.” –J Gill
2-2. FACT FINDING
"Grace and peace be multiplied unto you through the knowledge of God, and of Jesus our Lord" (2 Peter 1:2).
We cannot too highly value and appreciate heart-hunger for the Word. It is of the Spirit of Truth. We may have been born again without knowing much of the Bible, but we certainly are not going to grow to any extent apart from a careful and persistent study of the Word of God. Yes, the maturing believer is a Spirit-dependent student of the Scriptures, "whereby are given unto us exceeding great and precious promises; that by these ye might be partakers of the divine nature" (2 Peter 1.4).
"Christian progress is not a question of attaining to some abstract standard, or of pressing through to some far-off goal. It is wholly a question of seeing God's standard in God's Word. You advance spiritually by finding out what you really are (in Christ), not by trying to become what you hope to be. That goal you will never reach, however earnestly you may strive.
"It is when you see you are dead unto sin that you die to it (daily); it is when you see you are risen that you arise; it is when you see you are a 'new creation' in Him that you (progressively) grow. Seeing the accomplished fact in the Word determines the pathway to the realizing of that fact. The end is reached by seeing, not by desiring or working. The only possibility of spiritual progress lies in our discovering the truth as God sees it; the truth concerning Christ, the truth concerning ourselves in Christ." -W.N.
"Come and see the works of God" (Psalm 66:5).
