1 Peter 1:10-21
10 Concerning this salvation, the prophets who prophesied about the grace that was to be yours searched and inquired carefully, 11 inquiring what person or time the Spirit of Christ in them was indicating when he predicted the sufferings of Christ and the subsequent glories. 12 It was revealed to them that they were serving not themselves but you, in the things that have now been announced to you through those who preached the good news to you by the Holy Spirit sent from heaven, things into which angels long to look.
Called to Be Holy
13 Therefore, preparing your minds for action,  and being sober-minded, set your hope fully on the grace that will be brought to you at the revelation of Jesus Christ. 14 As obedient children, do not be conformed to the passions of your former ignorance, 15 but as he who called you is holy, you also be holy in all your conduct, 16 since it is written, “You shall be holy, for I am holy.” 17 And if you call on him as Father who judges impartially according to each one's deeds, conduct yourselves with fear throughout the time of your exile, 18 knowing that you were ransomed from the futile ways inherited from your forefathers, not with perishable things such as silver or gold, 19 but with the precious blood of Christ, like that of a lamb without blemish or spot. 20 He was foreknown before the foundation of the world but was made manifest in the last times for the sake of you 21 who through him are believers in God, who raised him from the dead and gave him glory, so that your faith and hope are in God.
