I was wondering, what does this mean, as said by a non-Catholic Christian “
It is biblical to work on ones own salvation before trying to help to save others”?
What does working on ones own salvation mean from a non-Catholic Christian perspective?
Thank you for your responses

It would depend on what sort of non-Catholic Christian said this. In fact, it would depend on your definition of “Christian.” A Baptist saying this could mean something different from a Presbyterian from a Lutheran from a Mormon (depending on if you consider them Christians).
If you are talking about Protestants, however, they would go to the Scriptures and see what the Bible says.
In Philippians 2:12-13 is written,
Therefore, my beloved, as you have always obeyed, so now, not only as in my presence but much more in my absence, work out your own salvation with fear and trembling, for it is God who works in you, both to will and to work for his good pleasure.
Notice that we don’t “work on” but we “work out” our salvation. It is God who must be at work in us “both to will and to work for his good pleasure.” In short, God works on us, and we work out the impacts of his grace and work in our lives.
Once again, it’s impossible to give specific “Protestant interpretation” to this text without knowing denominational affiliation, but we can speak in broad terms.
Broadly speaking, this verse displays the tension between the instantaneous and the progressive. It’s the tension between the subjective and the objective. It’s the tension between faith and work. This is a tension that runs throughout the Christian life. To work out one’s salvation is to be conformed into the image of Christ, as the potter molds the clay. It’s about brokenness. It’s about being emptied so that you can be filled.
In Philippians 1:27-30, Paul writes:
Only let your manner of life be worthy of the gospel of Christ, so that whether I come and see you or am absent, I may hear of you that you are standing firm in one spirit, with one mind striving side by side for the faith of the gospel, and not frightened in anything by your opponents. This is a clear sign to them of their destruction, but of your salvation, and that from God. For it has been granted to you that for the sake of Christ you should not only believe in him but also suffer for his sake, engaged in the same conflict that you saw I had and now hear that I still have.
We are to live a “worthy” life according to the gospel. We are to stand firm and strive for the faith with other believers. And we must not only believe in Christ but suffer for his sake because we are engaged in spiritual battle.
That being said, I don’t agree with the statement that we have to work on our own salvation before we help others come to the saving gospel. We are never going to be “perfect Christians.” Waiting to get everything together before you help spread the good news is an excuse for perpetual procrastination.
