When insulted or offended

“The vexation of a fool is known at once, but the prudent ignores an insult.” (Prov. 12:16 ESV)

Don’t take things to heart

“Do not take to heart all the things that people say, lest you hear your servant cursing you. Your heart knows that many times you yourself have cursed others.” (Eccles. 7:21-22 ESV)

Be slow to anger with good sense

“Know this, my beloved brothers: let every person be quick to hear, slow to speak, slow to anger.” (James 1:19 ESV)

“Good sense makes one slow to anger, and it is his glory to overlook an offense.” (Prov. 19:11 ESV)

Endure patiently with kindness 

“And the Lord's servant must not be quarrelsome but kind to everyone, able to teach, patiently enduring evil…” (2 Tim. 2:24 ESV)

Therefore…

“If you are insulted for the name of Christ, you are blessed, because the Spirit of glory and of God rests upon you.” (1 Peter 4:14 ESV)

“For the sake of Christ, then, I am content with weaknesses, insults, hardships, persecutions, and calamities. For when I am weak, then I am strong.” (2 Cor. 12:10 ESV)

“Blessed are you when people hate you and when they exclude you and revile you and spurn your name as evil, on account of the Son of Man! Rejoice in that day, and leap for joy, for behold, your reward is great in heaven; for so their fathers did to the prophets.” (Luke 6:22-23 ESV)

“The Lord will fight for you, and you have only to be silent.” (Exo. 14:14 ESV)

Quote: 

“Therefore, I bind these lies and slanderous accusations to my person as an ornament; it belongs to my Christian profession to be vilified, slandered, reproached and reviled, and since all this is nothing but that, as God and my conscience testify, I rejoice in being reproached for Christ's sake.” - John Bunyan
