'Working' in the Bible

(Because he who was working in Peter as the Apostle of the circumcision was working no less in me among the Gentiles);

He, therefore, who is supplying to you the Spirit, and working mighty acts among you -- by works of law or by the hearing of faith is it?

I am in fear of you, that I may have been working for you to no purpose.

But as at that time the child [of ordinary birth] born according to the flesh persecuted the son who was born according to [the promise and working of] the Spirit, so it is now also.

For in Christ Jesus neither circumcision nor uncircumcision accomplishes anything; what matters is faith working through love.
