'Work' in the Bible

convinced of this same [thing], that the one who began a good work in you will finish [it] until the day of Christ Jesus,

But if [it is] to live in the flesh, this [is] fruitful work for me, and which I will prefer [I do] not know.

Therefore my dear friends, just as you have always obeyed, not as in my presence only but now much more in my absence, work out your own salvation with fear and trembling.

For the one at work in you, both to will and to work for his good pleasure, is God.

because on account of the work of Christ he came near to the point of death, risking his life in order that {he might make up for your inability to serve me}.
