A simple question for theists

[Neo-Scholastic]

2 Tim chapter 3 starting @ 10 and going though chapter 4 ending at 8

There is a whole set up to this back of scripture. I do not understand why the chapter ended early/mid point. Anyway the crux of what is being discussed is where timothy can find the discernement he may need to navigate all the negitiv influences Paul is writing him about. This can be found in verse 16

16 All Scripture is given by God. (not just OT, as we live under the NT we are responsible for that as it has since been deemed Christian Scripture.) And all Scripture is useful for teaching and for showing people what is wrong in their lives. It is useful for correcting faults and teaching the right way to live. 17 Using the Scriptures, those who serve God will be prepared and will have everything they need to do every good work.

17 kinda sums it all up. If we seek to do a good work under God/a Work God would have us do, then it must by the book/scripture it must be done.

This is also supported in chapter 4:3 forward in that Paul identifies that their will be a time when people will want to stop listening the truth Timothy has derived from the scriptures, but Paul encourages him to stay the course even thought people aren't going to like what he has to say.

better yet in:
2peter 1:19 through the end of chapter 3

Peter illustrates by identifying false teachers of his day by using scripture against what these false teachers do and say. by the scripture he is able to identify several different sins from which these teachers build their ministries from.

So from Paul the over all "If you want to do a good deed for God a deed in which God has purposed for you (meaning along the lines of a life calling) then it is from the scripture (ALL OF IT NOT JUST THE OT) can you find ALL The info you need to COMPLETE Your task.

Then Peter delivers a sermon using what paul said to identify what plagued his own church/ministry. And He showed his congregation how 'false teachers' do not measure up against scripture.

First of all, none of this is God speaking, so no He didn't tell us not to accept any further revelations.  The passage in 2 Timothy indicates that the bible is sufficient, not that it is complete.  That's your own conclusion which you are adding to the text.  The text doesn't say anything about it being a complete set of God's revelations.  Since God does in fact order the killing of people in the bible, it's strictly your interpretation that the ordering of another killing would be contrary to what is in the bible.  In that I think you are wrong.  You simply used this 'no new revelations' line as a dodge to avoid answering the question.  Scripture doesn't back you up.

Other that the story of Abraham and Isaac, commandments to kill are nearly always proceeded by God pronouncing His judgement on those to be smitten. If the OP's hypothetical command followed the biblical template then there would be no doubt as to the reason for His judgment. Even then, blind obedience is not a requirement (SteveII take note). Prior to the destruction of Sodom, Abraham seems to have managed to stay God's hand at least until Lot and his daughters could escape.

With respect to Drich's scriptural references, throughout the OT God spoke through the prophets. They were authoritative. Likewise, Christians consider Paul and the other apostles authoritative, for various reasons. New revelations are always to be tested against prior revelations. For example:

"And He said to them, “O foolish men and slow of heart to believe in all that the prophets have spoken! Was it not necessary for the Christ to suffer these things and to enter into His glory?” Then beginning with Moses and with all the prophets, He explained to them the things concerning Himself in all the Scriptures." - Luke 24:25-27

That continuity is essential to the faith.
