'Stability' in the Bible

and having strapped on your feet the gospel of peace in preparation [to face the enemy with firm-footed stability and the readiness produced by the good news].

For even though I am absent in body, nevertheless I am with you in spirit, rejoicing to see your good discipline and the stability of your faith in Christ.

Therefore, dear friends, since you know this in advance, be on your guard, so that you are not led away by the error of lawless people and fall from your own stability.

For all that is in the world—the lust and sensual craving of the flesh and the lust and longing of the eyes and the boastful pride of life [pretentious confidence in one’s resources or in the stability of earthly things]—these do not come from the Father, but are from the world.
