2 Timothy 1:8 

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

Even when faced with persecution in this world, we cannot be ashamed of our Lord! We MUST rely on HIS power to make it through!

Romans 1:13 

For I am not ashamed of the gospel, for it is the power of God for salvation to all who believe. First to the Jew, then the Gentile.
