'Endurance' in the Bible

Be assured that the testing of your faith [through experience] produces endurance [leading to spiritual maturity, and inner peace].

And let endurance have its perfect result and do a thorough work, so that you may be perfect and completely developed [in your faith], lacking in nothing.

You know we call those blessed [happy, spiritually prosperous, favored by God] who were steadfast and endured [difficult circumstances]. You have heard of the patient endurance of Job and you have seen the Lord’s outcome [how He richly blessed Job]. The Lord is full of compassion and is merciful.
