be holy :)

Therefore, prepare your minds for action; be self-controlled; set your hope fully on the grace to be given you when Jesus Christ is revealed. As obedient children, do not conform to the evil desires you had when you lived in ignorance. But just as he who called you is holy, so be holy in all you do; for it is written: "Be holy, because I am holy. [Lev. 11:44,45; 19:2; 20:7]"

Since you call on a Father who judges each man's work impartially, live your lives as strangers here in reverent fear. For you know that it was not with perishable things such as silver or gold that you were redeemed from the empty way of life handed down to you from your forefathers, but with the precious blood of Christ, a lamb without blemish or defect.

For you have been born again, not of perishable seed, but of imperishable, through the living and enduring word of God. For,

"All men are like grass,
and all their glory is like the flowers of the field;
the grass withers and the flowers fall,
but the word of the Lord stands forever. [Isaiah 40:6-8]"

And this is the word that was preached to you.

Dear friends, I urge you, as aliens and strangers in the world, to abstain from sinful desires, which war against your soul. Live such good lives among the pagans that, though they accuse you of doing wrong, they may see your good deeds and glorify God on the day he visits us.

Therefore, since Christ suffered in his body, arm yourselves also with the same attitude, because he who has suffered in his body is done with sin. As a result, he does not live the rest of his earthly life for evil human desires, but rather for the will of God. For you have spent enough time in the past doing what pagans choose to do—living in debauchery, lust, drunkenness, orgies, carousing and detestable idolatry. They think it strange that you do not plunge with them into the same flood of dissipation, and they heap abuse on you. But they will have to give account to him who is ready to judge the living and the dead. For this is the reason the gospel was preached even to those who are now dead, so that they might be judged according to men in regard to the body, but live according to God in regard to the spirit.
