It is a sin to question God's authority or ways/decisions (it's not a sin to question why), although you are write in saying that this isn't a parable about sin, but it's about those who had labored for God longer then those freshly coming in and they were clearly in the wrong by their thinking, for Christ rebuked them in the story. The parable is about our attitude toward new comers or late comers into the faith, it clearly stating that we should refrain from resentment because God loves those late comers just the same. This parable probably has more to do with the Jews who are saved but then are looking down on the gentiles who also believed are are saved. But sure it has application for us today...
Also, regarding Acts 2:47 and the rendering of "should" be saved, all I have to say is the KJV strikes again!
NKJV
[SUP]47 [/SUP]praising God and having favor with all the people. And the Lord added to the church[SUP][h][/SUP] daily those who were being saved.
Expanded bible
[SUP]47 [/SUP]They praised God and were ·liked by [looked upon favorably by] all the people. Every day the Lord added those who were being saved to the group of believers.
Youngs literal translation
[SUP]47 [/SUP]praising God, and having favour with all the people, and the Lord was adding those being saved every day to the assembly.

Bookends. we are getting there.... the first thing I want you to see is.... LOOK, all these verses you qouted in blue, says.... The people STILL NEED SAVING... They are NOT SAVED YET!!!! Do you see they are STILL IN THE SAVING process?
They still need to be saved. Now let us shift our focus to holy people that GOD SAVED! God saved them not busy saving them. The ones God SAVED! Completely SAVED! The ones God says, are IN CHRIST! not being brought into Christ, they are ALREADY IN CHRIST! You see SALVATION IS IN Christ.... IN HIM! All SAVED people are IN HIM, and the ones that NEED SAVING, are being made to BE IN HIM. They are NOT IN HIM YET... they are BEING MADE HOLY to be in HIM! They are NOT HOLY YET, that is why they NEED SAVING, or BEING SAVED....
God says we know we are IN HIM when we sin no more! If we still sin, we are NOT IN HIM YET, and we are still like these people BEING SAVED... But Satan infiltrated the church and MISLEAD many... Satan is the one that says we CANNOT be holy, WE cannot be perfect. Satan made HIS OWN REIGHTEOUSNESS.... the one that says... Do not worry, Jesus died for your sins. That is a LIE! Jesus died for the sins people REPENT FROM, because He DIED ONCE, and was resurrected to BRING A NEW LIFE TO ALL WHO HE DIED FOR! HE (Christ Jesus) is the NEW LIFE in all whom he SAVED!
God says those that are being made Holy and He that makes holy ARE OUT OF ONE! Heb 2:11.... But how can a person be out of the SAME one that makes holy if the person do not believe in holiness. Godly holiness, as Holy AS GOD IS HOLY! I believe the one that makes HOLY does so PERFECTLY! And the one that are being made holy (being saved) will end up as holy and as perfect as God when the ONE who makes Holy is finished.... Right here on earth, and that person is SAVED!
