'Persistent' in the Bible

to those on the one hand who, by lives of persistent right-doing, are striving for glory, honour and immortality, the Life of the Ages;

full of joyful hope, patient under persecution, earnest and persistent in prayer.

For we never fail to remember your works of faith and labours of love and your persistent and unwavering hope in our Lord Jesus Christ in the presence of our God and Father;

and persistent wranglings on the part of people whose intellects are disordered and they themselves blinded to all knowledge of the truth; who imagine that godliness means gain.
