'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 be 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.

not purloining, but showing all good stedfastness, that the teaching of God our Saviour they may adorn in all things.

Wherefore, having girded up the loins of your mind, be sober and hope with perfect stedfastness in the grace which will be brought to you at the revelation of Jesus Christ;

Ye therefore, beloved, seeing ye know these things before, beware lest ye also, being led away with the error of the wicked, fall from your own stedfastness.
