'Persevering' in the Bible

Create in me a clean heart, O God,And renew a right and steadfast spirit within me.

Happy [is] the [one who is] persevering, and attains [to] [the] one thousand three hundred and thirty-five days.

in the hope rejoicing; in the tribulation enduring; in the prayer persevering;

And so by persevering, Abraham inherited the promise.

Everyone who hates (works against) his brother [in Christ] is [at heart] a murderer [by God’s standards]; and you know that no murderer has eternal life abiding in him.
