1 Peter 1:6-23
[6]So be truly glad. There is wonderful joy ahead, even though you must endure many trials for a little while.
[7]These trials will show that your faith is genuine. It is being tested as fire tests and purifies gold—though your faith is far more precious than mere gold. So when your faith remains strong through many trials, it will bring you much praise and glory and honor on the day when Jesus Christ is revealed to the whole world.
[8]You love him even though you have never seen him. Though you do not see him now, you trust him; and you rejoice with a glorious, inexpressible joy.
[9]The reward for trusting him will be the salvation of your souls.
[10]This salvation was something even the prophets wanted to know more about when they prophesied about this gracious salvation prepared for you.
[11]They wondered what time or situation the Spirit of Christ within them was talking about when he told them in advance about Christ’s suffering and his great glory afterward.
[12]They were told that their messages were not for themselves, but for you. And now this Good News has been announced to you by those who preached in the power of the Holy Spirit sent from heaven. It is all so wonderful that even the angels are eagerly watching these things happen.
[13]So prepare your minds for action and exercise self-control. Put all your hope in the gracious salvation that will come to you when Jesus Christ is revealed to the world.
[14]So you must live as God’s obedient children. Don’t slip back into your old ways of living to satisfy your own desires. You didn’t know any better then.
[15]But now you must be holy in everything you do, just as God who chose you is holy.
[16]For the Scriptures say, “You must be holy because I am holy.”
[17]And remember that the heavenly Father to whom you pray has no favorites. He will judge or reward you according to what you do. So you must live in reverent fear of him during your time here as “temporary residents.”
[18]For you know that God paid a ransom to save you from the empty life you inherited from your ancestors. And it was not paid with mere gold or silver, which lose their value.
[19]It was the precious blood of Christ, the sinless, spotless Lamb of God.
[20]God chose him as your ransom long before the world began, but now in these last days he has been revealed for your sake.
[21]Through Christ you have come to trust in God. And you have placed your faith and hope in God because he raised Christ from the dead and gave him great glory.
[22]You were cleansed from your sins when you obeyed the truth, so now you must show sincere love to each other as brothers and sisters. Love each other deeply with all your heart.
[23]For you have been born again, but not to a life that will quickly end. Your new life will last forever because it comes from the eternal, living word of God.
Always wondered about "Be Holy AS YOUR FATHER is Holy", and "without Holiness no one will see the Lord", found good piece from MaClaren;
I. The Pattern of Holiness.
‘As He that hath called you is holy.’ God’s holiness is the very attribute which seems to separate Him most from the creatures; for its deepest meaning is His majestic and Divine elevation above all that is creatural. But here, of course, the idea conveyed by the word is not that, if I may so say, metaphysical one, but the purely moral one. The holiness of God which is capable of imitation by us is His separation from all impurity. There is a side of His holiness which separates Him from all the creatures, to which we can only look up, or bow with our faces in the dust; but there is a side of His holiness which, wonderful as it is, and high above all our present attainment as it is, yet is not higher than the possibilities which His indwelling Spirit puts within our reach, nor beyond the bounds of the duty that presses upon us all. ‘As He which hath called you is holy.’ Absolute and utter purity is His holiness, and that is the pattern for us.
Religion is imitation. The truest form of worship is to copy. All through heathenism you find that principle working. ‘They that make them are like unto them.’ Why are heathen nations so besotted and sunken and obstinate in their foulnesses? Because their gods are their examples, and they, first of all, make the gods after the pattern of their own evil imaginations, and then the evil imaginations, deified, react upon the maker and make him tenfold more a child of hell than themselves. Worship is imitation, and there is no religion which does not necessarily involve the copying of the example or the pattern of that Being before whom we bow. For religion is but love and reverence in the superlative degree, and the natural operation of love is to copy, and the natural operation of reverence is the same. So that the old Mosaic law, ‘Be ye holy as I am holy,’ went to the very heart of religion. And the New Testament form of it, as Paul puts it in a very bold word, ‘Be ye imitators of God, as beloved children,’ sets its seal on the same thought that we are religious in the proportion in which we are consciously copying and aspiring after God.
But then, says somebody or other, ‘it is not possible.’ Well, if it were not possible, try it all the same. For in this world it is aim and not attainment that makes the noble life; and it is better to shoot at the stars, even though your arrow never reaches them, than to fire it along the low levels of ordinary life. I do not see that however the unattainableness of the model may be demonstrated, that has anything to do with the duty of imitation. Because, though absolute conformity running throughout the whole of a life is not possible here on earth, we know that in each individual instance in which we came short of conformity the fault was ours, and it might have been otherwise. Instead of bewildering ourselves with questions about ‘unattainable’ or ‘attainable,’ suppose we asked, at each failure, ‘Why did I not copy God then; was it because I could not, or because I would not?’ The answer would come plain enough to knock all that sophisticated nonsense out of our heads, and to make us feel that the law which puts an unattainable ideal before the Christian as his duty is an intensely practical one, and may be reduced to practice at each step in his career. Imitation of the Father, and to be perfect, ‘as our Father in heaven is perfect,’ is the elementary and the ultimate commandment of all Christian morality. ‘Be ye holy as He that hath called you is holy.’
Then let me remind you that the unattainableness is by no means so demonstrable as some people seem to think. A very tiny circle may have the same centre as one that reaches beyond the suburbs of the universe, and holds all stars and systems within its great round. And the tiniest circle will have the same geometrical laws applied to it as the greatest. The difference between finite and infinite has nothing to do with the possibility of our becoming like God, if we believe that ‘in the image of God created He him’; and that men who have been not only made by original creation in the Divine image, but have been born again by the incorruptible seed of the Word into a kindred life with His, and derived from Him, can surely grow like what they have got, and unfold into actually possessed and achieved resemblance to their Father the kindred life that is poured into their veins.
So every way it is better indefinitely to approximate to that great likeness, though with many flaws and failures, than to say it cannot be reached, and so I will content myself down here, in my sins and my meannesses. No! dear brethren, ‘we are saved by hope,’ and one prime condition of growth in nobleness is to believe it possible that, by His blessing we may be like Him here on earth in the measure of our perception of His beauty and reception of His grace.
