I'm starting to kinda get the impression 1 Corinthians 3:10-15 is talking about how we'll be changed. The bad works will be removed and the good works will remain. We'll be better than before.
I can see what you are saying but I cannot see what you are saying in the verses in 1 Corinthians 3.
With regards to being changed where bad works are removed and good works will remain I see this as sanctification.
I suppose it comes down to the "works" in Corinthians and what those works are.
Are the works in Corinthians works of the fruit of the Holy Spirit?
Or are they what we tell/preach/teach based on the foundation that Paul talks about.
We see Paul introduced the gospel given to by Jeus to preach to the gentiles.
So he has laid a foundation that is basically the starting point.
What is the starting point?
Paul states this in other letters he wrote.
Saved by faith, through grace (just like he was)
In Romans
Romans 10:8-13
8 But what does it say? “The word is near you, in your mouth and in your heart” (that is, the word of faith which we preach): 9 that if you confess with your mouth the Lord Jesus and believe in your heart that God has raised Him from the dead, you will be saved. 10 For with the heart one believes unto righteousness, and with the mouth confession is made unto salvation. 11 For the Scripture says, “Whoever believes on Him will not be put to shame.” 12 For there is no distinction between Jew and Greek, for the same Lord over all is rich to all who call upon Him. 13 For “whoever calls on the name of the Lord shall be saved.”
Is this the foundation Paul is talking about in Corinthians?
If so then is Paul stating "Be careful not add more to that?
Paul cannot call the Corinthian Christians ''spiritual'' people. Though they are in Christ, they continue to live to the flesh. They are spiritual infants, not ready for solid food. Divisions among them prove they are still serving themselves, picking sides in a senseless debate between Christian teachers. Paul insists that both he and Apollos are mere servants of the Lord and co-workers. They are not in competition. Those who lead the Corinthians must build carefully because their work will be tested on the day of the Lord. Christian leaders who build the church will have their work judged by Christ to see if they have built on the foundation of Christ. All human wisdom will be shown to be futile and worthless.

The reason I think it's based on teaching over and above this is because Paul in other letters talks about walking according the fruit of the Holy Spirit.
Also
James 3:1
The Untamable Tongue
1 My brethren, let not many of you become teachers, knowing that we shall receive a stricter judgment.
Is this what Paul is talking about also?
He calls them brothers.
