Concerning this salvation, prophets who prophesied about the grace that was to be yours searched and investigated it, investigating the time and circumstances that the Spirit of Christ within them indicated when it testified in advance to the sufferings destined for Christ and the glories to follow them.It was revealed to them that they were serving not themselves but you with regard to the things that have now been announced to you by those who preached the good news to you [through] the holy Spirit sent from heaven, things into which angels longed to look.Source
Therefore, gird up the loins of your mind, live soberly, and set your hopes completely on the grace to be brought to you at the revelation of Jesus Christ. Like obedient children, do not act in compliance with the desires of your former ignorance but, as he who called you is holy, be holy yourselves in every aspect of your conduct, for it is written, “Be holy because I [am] holy.” Now if you invoke as Father him who judges impartially according to each one’s works, conduct yourselves with reverence during the time of your sojourning, realizing that you were ransomed from your futile conduct, handed on by your ancestors, not with perishable things like silver or gold but with the precious blood of Christ as of a spotless unblemished lamb. He was known before the foundation of the world but revealed in the final time for you, who through him believe in God who raised him from the dead and gave him glory, so that your faith and hope are in God.
Since you have purified yourselves by obedience to the truth for sincere mutual love, love one another intensely from a [pure] heart.You have been born anew, not from perishable but from imperishable seed, through the living and abiding word of God,>for:
'All flesh is like grass, and all its glory like the flower of the field; the grass withers, but the word of the Lord remains forever.'”
