'Persevere' in the Bible

Whoever does not carry his own cross [expressing a willingness to endure whatever may come] and follow after Me [believing in Me, conforming to My example in living and, if need be, suffering or perhaps dying because of faith in Me] cannot be My disciple.

Pay close attention to yourself [concentrate on your personal development] and to your teaching; persevere in these things [hold to them], for as you do this you will ensure salvation both for yourself and for those who hear you.

For this reason I [am ready to] patiently endure all things for the sake of those who are the elect (God’s chosen ones), so that they too may obtain the salvation which is in Christ Jesus and with it the reward of eternal glory.

By Silvanus, our faithful brother (as I consider him), I have written to you briefly, to counsel and testify that this is the true grace [the undeserved favor] of God. Stand firm in it!

Watch yourselves, so that you do not lose what we have accomplished together, but that you may receive a full and perfect reward [when He grants rewards to faithful believers].
