I don't know - picking these verses out in defense of the idea that YOU are credited for a part of your salvation seems like it goes against Paul's claim that says God's free gift of grace leaves us unable to boast.
Ephesians 2:4-9 ~
But because of His great love for us, God, who is rich in mercy, 5made us alive with Christ, even when we were dead in our trespasses. It is by grace you have been saved! And God raised us up with Christ and seated us with Him in the heavenly realms in Christ Jesus, in order that in the coming ages He might display the surpassing riches of His grace, demonstrated by His kindness to us in Christ Jesus.
For it is by grace you have been saved through faith, and this not from yourselves; it is the gift of God, not by works, so that no one can boast.
Acts of the Apostles 2 (more in context) says this. Notice what they're being saved FROM:
Acts 2:36-40 ~ Therefore let all Israel know with certainty that God has made this Jesus, whom you crucified, both Lord and Christ!”
Three Thousand Believe
When the people heard this, they were cut to the heart and asked Peter and the other apostles, “Brothers, what shall we do?”
Peter replied, “Repent and be baptized, every one of you, in the name of Jesus Christ for the forgiveness of your sins, and you will receive the gift of the Holy Spirit. This promise belongs to you and your children and to all who are far off—to all whom the Lord our God will call to Himself.”
With many other words he testified, and he urged them, “Be saved from this corrupt generation.
1 Timothy 4:16 in context says: A Good Minister of Jesus Christ
(Leviticus 21:1-17) v 14-16 ~ Do not neglect the gift that is in you, which was given you through the prophecy spoken over you at the laying on of the hands of the elders. Be diligent in these matters and absorbed in them, so that your progress will be evident to all. Pay close attention to your life and to your teaching. Persevere in these things, for by so doing you will save both yourself and those who hear you.
(I don't see that as an issue of salvation, but of sanctification. Also - this is believed to have been written around 56 A.D.....and following the "right" group and sound teaching was a matter of physical life and death [besides spiritual] with the impending destruction of the Temple and Jerusalem.
2 Corinthians 7 expanded to include 2 Corinthians 6:16-18 for context:
What agreement can exist between the temple of God and idols? For we are the temple of the living God. As God has said: “I will live with them and walk among them, and I will be their God, and they will be My people.” “Therefore come out from among them and be separate, says the Lord. Touch no unclean thing, and I will receive you.” And: “I will be a Father to you, and you will be My sons and daughters, says the Lord Almighty.”
2 Corinthians 7:1 ~ Therefore, beloved, since we have these promises, let us cleanse ourselves from everything that defiles body and spirit, perfecting holiness in the fear of God.
I also see that as a response to His gift - our sanctification process that flows from our belief.
I don't see that as any different than what I had posted here (with the exception that you're claiming cooperation in your SALVATION). I don't believe we cooperated in our salvation - He alone defeated sin:
God saves. The issue is WHO does He save and WHY?
The "who" that God saves is anyone and the "why" is obedience. God will save anyone who will faithfully obey His word. So those in Acts 2 that faithfully obeyed God's command to repent and be baptized are the ones God saves. Since God does not force people to repent and be baptized but they chose of their free will to do so, in that sense Peter is saying to them 'save yourselves' by obeying God's command.
Much like a person who is drowning and someone throws a life preserver and yells to the drowning person "grab hold of the preserver and save yourself". And by grabbing hold he does have a role in his own salvation. It took BOTH the preserver to be thrown to him AND him grabbing hold of it to be saved.
In similar manner, God threw a life preserver in the form of Jesus Christ to men drowning in sin. God says obey Christ and be saved (Hebrew 5:9) and those that do in that sense save themselves.
Salvation is not 100% God doing everything....in randomly, unconditionally choosing which certain individuals will or will not be saved, forcing certain men to grab the life preserver (force men to repent and be baptized), etc. God has provided the means to be saved (repent and be baptized) but is still up to man to take advantage of what God has provided by obeying what God command. If a man sits idle then he is bypassing, forsaking the only means God has given him for him to be saved.
So the verses that say "save yourselves" "save thyself" and "cleansed ourselves", etc show that men are to grab hold of that preserver (Jesus Christ) and be saved.
Doing nothing leaves one lost, drowning in sin.
Obedience to God is nothing to boast about..."
So likewise ye, when ye shall have done all those things which are commanded you, say, We are unprofitable servants: we have done that which was our duty to do."
Man has a DUTY to obey God but man will not be sinlessly perfect in his obedience leaving man an unprofitable servant in need of grace. Yet those who do their duty and obey God, and repent for those times they come up short are the ones who receive grace. Those who do nothing, do not obey are derelict in their duty. Luke 13:24 the word 'strive' means to agonize over, contend, struggle with great difficulty to enter the strait gate by doing all one can to do his duty in obeying God's will. Doing nothing/not obeying what God has commanded will keep one from entering thru the strait gate.
.
Persevere in these things, for by so doing you will save both yourself and those who hear you. 1 Timothy 4:16
You posted "
I don't see that as an issue of salvation, but of sanctification"
Again, Paul said to Timothy "SAVE thyself" not "sanctify thyself"
