Verses will be quoted and afterward my comments with original words and other English translations:
A. Heb 12:2 “Looking unto Jesus the (author and finisher) of our faith; who for the joy that was set before him endured the cross, despising the shame, and is set down at the right hand of the throne of God.”
COMMENT: Being the author (archegos/chief leader, predecessor) and finisher (teleiotes/consummated, perfecter, set before us the highest example of faith)… means that he started or originated this faith, and he consummated or “perfected” it. As important as our individual faiths in God are, it’s the faith (of) Jesus, the only faith that counts and makes any difference. Notice the following verses:
Romans 3:22 “Even the righteousness of God which is by faith (of) Jesus Christ unto all and upon all them that believe”. His faith is imputed to us all.
Galatians 2:16 “Knowing that a man is not justified by the works of the law, but by the faith (of) Jesus Christ, even we have believed in Jesus Christ, that we might be justified by the faith of Christ, and not by the works of the law: for by the works of the law shall no flesh be justified.” (Notice, “even we have believed in” JC).
Galatians 3:22 “But the scripture hath concluded all under sin, that the promise by faith (of) Jesus Christ might be given to them that believe.” (Notice, because of faith of JC that the promise of the Holy Spirit was given).
Philippians 3:9 “And be found in him, not having mine own righteousness, which is of the law, but that which is through the faith (of) Christ, the righteousness which is of God by faith”
B. Phil..1:6 “Being confident of this very thing, that he which hath begun a good work in you will perform/ (epiteleo,complete) it until the day of Jesus Christ”.
COMMENT: Paul was expressing his v-20 “… earnest expectation..” God’s work in this period of time will be completed (Jesus the finisher) by the time (until) Jesus returns. In this period of time, prior to Jesus’ second coming, God is working in us, having started this work through the Spirit given to us. This work will be completed for the “firstfruits” or “first harvest”, but not for all, in this period of time. At the second coming, there will be “work” that continues for a Millenium, for the “latter fruits or “second harvest”.
The assumption that God, being most powerful, will be the sole deciding factor in our faith, smacks down and takes away our free will. No one will be coerced into submission. The Father does not want “robots”. Such an enormous and magnificent “gift” will not be forced onto us. Proof of the matter comes with what happened to the “first begotten Son of God”, Jesus. At the garden of Gethsemane (Luke 22:42), he was not forced to “drink the cup”, even when he himself acknowledged that as far as he was concerned, he would “Let this cup pass”. But, the action he took was his free will, and humbly asked God the Father, “Let it be your will and not mine”.
As Jesus (not just the Father) was also a deciding factor, similarly our role cannot be negated; but voluntarily we should “all” say, “Let it be God’s will”. That is why, as Jesus has faith in the Father, we also have to have faith, even when the only faith that counts is the faith (of) Jesus, that faith being the original, the start and the complete one. Remember, “from faith-to-faith”.
