'Stedfastness' in the Bible

And not only so, but we also rejoice in our tribulations: knowing that tribulation worketh stedfastness;

and stedfastness, approvedness; and approvedness, hope:

For though I am absent in the flesh, yet am I with you in the spirit, joying and beholding your order, and the stedfastness of your faith in Christ.

Ye therefore, beloved, knowing these things beforehand, beware lest, being carried away with the error of the wicked, ye fall from your own stedfastness.
