'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.
But whatever be the point that we have already reached, let us persevere in the same course.
Persevere in prayer, watching in it with thanksgiving;
Pay close attention to your life and your teaching; persevere in these things, for by doing this you will save both yourself and your hearers.
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].
