'Steadfastness' in the Bible

enabled with all power, according to his glorious might, for all steadfastness and patience with joy,

for even if I am absent in the flesh, yet I am with you in spirit, rejoicing and seeing your good order and the steadfastness of your faith in Christ.

[because we] remember your work of faith and labor of love and steadfastness of hope in our Lord Jesus Christ in the presence of our God and Father,

I, John, your brother and co-sharer in the affliction and kingdom and steadfastness in Jesus, was on the island called Patmos because of the word of God and the testimony about Jesus.
