'Working' in the Bible

I am convinced of this, and I know that I shall remain, and shall go on working side by side with you all, to promote your progress and joy in the faith;

Just one thing: Live your life in a manner worthy of the gospel of Christ. Then, whether I come and see you or am absent, I will hear about you that you are standing firm in one spirit, with one mind, working side by side for the faith that comes from the gospel,

So then, my dear friends, just as you have always obeyed, not only in my presence but even more in my absence, continue working out your salvation with awe and reverence,

For it is God who is working in you, enabling you both to desire and to work out His good purpose.

But you know his qualifications, that like a son working with his father, he served with me in advancing the gospel.

because he came close to death for the work of Christ, risking his life to complete what was lacking in your service to me [which distance prevented you from rendering personally].

Who shall change our vile body, that it may be fashioned like unto his glorious body, according to the working whereby he is able even to subdue all things unto himself.
