And your point is? I don't think you are refuting anything I posted.
First, Jesus is the Son of God. He did not have to learn anything, let alone obedience. Treat "learn" not as expansion of his knowledge, but completion of an experience, aka being schooled.
Secondly, note two meanings of perfect.
1) be without sin, fault
2) complete
As my original post stated, Jesus was always perfect in the sense of being sinless, that would include being obedient. What you completely ignore in the text that I quoted is the word suffered. Why did Jesus die if all that is needed for salvation is obedience? There is an important reason why Jesus died. Jesus completed God's plan of redemption with his death/suffering. Jesus even said it.
John 19:30 When he had received the drink, Jesus said, “It is
finished.” With that, he bowed his head and gave up his spirit.
Now your attempt to discredit "grace doctrine". I am not going to quote exact scripture that says we are saved by grace. I am sure you have already figured out a way to ignore those texts.
I just ask a simple question. How perfectly must we obey God's commands for us to be saved? You kid yourself if you think you can do it perfectly. So is one sin a day or a week or a month good enough to deserve salvation? Why did Jesus die if we could be perfect through obedience?
Romans 11:6 And if by
grace, then it cannot be based on works; if it were,
grace would no longer be
grace.
We should try to stay on topic; which is to do with perfection; the original post as I recall compared Matt 5:48 with a secular statement "It is impossible to be perfect"; which is to compare oranges with apples. The perfection mentioned in Hebrews 5:48 is defined in the previous verses; in the secular statement however "perfect" is not defined.
The scriptures defined "perfect" you will notice:
Psalm 18:30 (ASV)
30 As for God, his way is perfect: The word of Jehovah is tried; He is a shield unto all them that take refuge in him.
Psalm 19:7 (ASV)
7 The law of Jehovah is perfect, restoring the soul: The testimony of Jehovah is sure, making wise the simple.
Psalm 37:37 (ASV)
37 Mark the perfect man, and behold the upright; For there is a
happy end to the man of peace.
Psalm 101:2 (ASV)
2 I will behave myself wisely in a perfect way: Oh when wilt thou come unto me? I will walk within my house with a perfect heart.
Psalm 101:6 (ASV)
6 Mine eyes shall be upon the faithful of the land, that they may dwell with me: He that walketh in a perfect way, he shall minister unto me.
Psalm 138:8 (ASV)
8 Jehovah will perfect that which concerneth me: Thy lovingkindness, O Jehovah,
endureth for ever; Forsake not the works of thine own hands.
"Son of God' and "son of man" are Hebrew idioms. Hebrew 5:5 ... Thou art my Son, I to-day have begotten thee;. This is a paraphrase from His baptism.
Hebrews 5:8-9 (ASV)
8 though he was a Son, yet learned obedience by the things which he suffered;
9 and having been made perfect, he became unto all them that obey him the author of eternal salvation;
You seem to be disputing or rephrasing these scriptures; while I reject other aspects of Hebrews I have never questioned this part.
The applications for the word perfect are endless; the is a basic concept that implies excellence but in religion the word is often used in a mystical or irrational way.
Regarding John 19:30; instead of it is finished Jesus could have said, it is perfect, except the grammar is changed; it all depends on what "it" refers to.
Paul is hard to fault but there are errors in his theology; Paul speaks most about Grace, Dispensationalism introduces the Gospel of Grace, even if Paul used the words; Dispensationalism does not use Paul's meaning.
To say the doctrine of grace is discredited implies the doctrine has had credit; the doctrine of grace is a doctrine of men and as such is a perfect example of trying to put words in God's mouth while discrediting everything He actually said.
The answer to your simple question is there is not a list of what to do; everybody's situation is unique, but all of God's word is to that end; God makes the simple wise so the do not need to ask the question.
