'Steadfast' in the Bible

But as for the seed that landed on good soil, these are the ones who, after hearing the word, cling to it with an honest and good heart, and bear fruit with steadfast endurance.

And our hope for you is steadfast because we know that as you share in our sufferings, so also you will share in our comfort.

We have this hope as an anchor for the soul, sure and steadfast, which reaches inside behind the curtain,

I know your works as well as your labor and steadfast endurance, and that you cannot tolerate evil. You have even put to the test those who refer to themselves as apostles (but are not), and have discovered that they are false.

I know your deeds: your love, faith, service, and steadfast endurance. In fact, your more recent deeds are greater than your earlier ones.

If anyone is meant for captivity, into captivity he will go. If anyone is to be killed by the sword, then by the sword he must be killed. This requires steadfast endurance and faith from the saints.

This requires the steadfast endurance of the saints -- those who obey God's commandments and hold to their faith in Jesus.
