'Suffering' in the Bible

So don’t be ashamed of the testimony about our Lord, or of me His prisoner. Instead, share in suffering for the gospel, relying on the power of God.

This is why I suffer as I do. Still, I am not ashamed; for I know Him [and I am personally acquainted with Him] whom I have believed [with absolute trust and confidence in Him and in the truth of His deity], and I am persuaded [beyond any doubt] that He is able to guard that which I have entrusted to Him until that day [when I stand before Him].

Share in suffering as a good soldier of Christ Jesus.

for that [gospel] I am suffering even to [the point of] wearing chains like a criminal; but the word of God is not chained or imprisoned!

But you must be clear-headed about everything. Endure suffering. Do the work of an evangelist. Devote yourself completely to your ministry.
