1Peter 3.13-17, 18
Now who will harm you if you are eager to do what is good?  But even if you do suffer for doing what is right, you are blessed. Do not fear what they fear, and do not be intimidated, but in your hearts sanctify Christ as Lord. Always be ready to make your defense to anyone who demands from you an accounting for the hope that is in you; yet do it with gentleness and reverence. Keep your conscience clear, so that, when you are maligned, those who abuse you for your good conduct in Christ may be put to shame.  For it is better to suffer for doing good, if suffering should be God’s will, than to suffer for doing evil.  For Christ also suffered for sins once for all, the righteous for the unrighteous, in order to bring you to God. He was put to death in the flesh, but made alive in the spirit,

Isaiah 49.22-23 / Romans 10.11
Thus says the Lord God:
I will soon lift up my hand to the nations,
    and raise my signal to the peoples;
and they shall bring your sons in their bosom,
    and your daughters shall be carried on their shoulders.
Kings shall be your foster fathers,
    and their queens your nursing mothers.
With their faces to the ground they shall bow down to you,
    and lick the dust of your feet.
Then you will know that I am the Lord;
    those who wait for me shall not be put to shame.

Acts 22.19-21
And I said, ‘Lord, they themselves know that in every synagogue I imprisoned and beat those who believed in you.  And while the blood of your witness Stephen was shed, I myself was standing by, approving and keeping the coats of those who killed him.’  Then he said to me, ‘Go, for I will send you far away to the Gentiles.’”
