Saints Peter and Paul on Holiness

Simply proclaim the Lord Christ holy in your hearts, and always have your answer ready for people who ask you the reason for the hope that you have. But give it with courtesy and respect and with a clear conscience, so that those who slander your good behaviour in Christ may be ashamed of their accusations.

— St. Peter from 1 Peter 3:15-16

I remind you to stir into flame the gift of God that you have through the imposition of my hands. For God did not give us a spirit of cowardice but rather of power and love and self-control. So do not be ashamed of your testimony to our Lord, nor of me, a prisoner for his sake; but bear your share of the hardship for the gospel with the strength that comes from God. 

— St. Paul from 2 Timothy 1:6-8
