Peter (like Paul) builds application on doctrinal truths. 1 Peter 1: 13 begins with "Therefore" so when you see it you should go back and see why it's "there for"
The previous verses gave us 5 important pieces of information....
1. Vs 1 You are one of the Elect (chosen/selected)
You have been chosen. How do you know that you have been chosen? If at some point in your life (or in the future) you have been called by the Holy Spirit (wooed/ drawn) you are then chosen.
2. Vs 3 He caused you to be born again
God did not force you to be born again, but He made provisions for forgiveness, reconciliation, New Birth. It was nothing that you did on your own, He draws you to be born again.
3. Vs 4 He has given you an imperishable inheritance
Your inheritance is waiting for you until you get there (heaven). Your inheritance is unfading like an earthly inheritance.
4. Vs 5 You are being guarded by God's power
You are being kept by His grace not your own goodness
Jude 24-25 (ESV) "Now to him who is able to keep you from stumbling and to present you blameless before the presence of his glory with great joy, to the only God, our Savior, through Jesus Christ our Lord, be glory, majesty, dominion, and authority, before all time and now and forever. Amen."
1 Peter 1: 6-7 (ESV) "In this you rejoice, though now for a little while, if necessary, you have been grieved by various trials, so that the tested genuineness of your faith- more precious than gold that perishes though it is tested by fire- may be found to result in praise and glory and honor at the revelation of Jesus Christ."
All this goodness that has happened to you in your life is because of God. You will go through trials. The trials are designed to refine your faith, not destroy your faith.
Romans 8:28 (ESV) "And we know that for those who love God all things work together for good, for those who are called according to his purpose."
5. Vs 9 You are obtaining the outcome of your faith
The salvation of your soul....eternal life
1 Peter 1: 10-12 (ESV) "Concerning this salvation, the prophets who prophesied about the grace that was to be yours searched and inquired carefully, inquiring what person or time the Spirit of Christ in them was indicating when he predicted the sufferings of Christ and subsequent glories. 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."
The prophets inquired about and wondered about it, angels "long to look into this"... this mystery to them is fulfilled in you. They stand in AWE of the Gospel.
1 Peter 1: 13-19 (ESV) "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. As obedient children, do not be conformed to the passions of your former ignorance, but as he who called you is holy, you also be holy in all your conduct, since it is written, 'You shall be holy, for I am holy.' 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, knowing that you were ransomed from the futile was inherited from your forefathers, not with perishable things such as silver or gold, but with the precious blood of Christ, like that of a lamb without blemish or spot."
I. Prepare your Mind...for Action!
Prepare your mind to do something! A Christian's life is not just heart and head but also HANDS. Prepare your hands.
James 2:17 (ESV) "So also faith by itself, if it does not have works, is dead."
Matt. 7:24 (ESV) "Everyone then who hears these words of mine and does them will be like a wise man who built his house on the rock."
Repentance is a change of heart and mind, but if there is not a change in action then it is dead. Repentance is a 180 deg. turn....it is an action.
II Be Sober Minded (not under the influence)
Be self controlled
Ephesians 5:15-18 (ESV) "Look carefully then how you walk, not as unwise but as wise, making the best use of the time, because the days are evil. Therefore do not be foolish, but understand what the will of the Lord is. And do not get drunk with wine, for that is debauchery, but be filled with the Spirit."
Think straight, use your head. Be controlled by God not alcohol/drugs.
III. Do not be conformed to your (sinful) passions.
God created us to be passionate beings. We have a lot of emotions/feelings. Your emotions are not your lord.
Jer. 17:19 (ESV) "Be not a terror to me; you are my refuge in the day of disaster. Let those be put to shame who persecute me, but let me not be put to shame; let them be dismayed, but let me not be dismayed; bring upon them the day of disaster; destroy them with double destruction! Thus said the LORD to me: 'Go and stand in the People's Gate, by which the kings of Judah enter and by which they go out, and in all the gates of Jerusalem,'"
People say to follow your heart, but your heart is damaged...if your emotions /feelings are aligned with God's will then go ahead and be passionate.
Romans 12:2 (ESV) "Do not be conformed to this world, but be transformed by the renewal of your mind, that by testing you may discern what is the will of God, what is good and acceptable and perfect."
Follow God's will in all you do...marriage, career, hobby, sexual activity. The world is not aligned with God's will.
IV. Set your hope (expectations) on His grace
Do not set your hope on your own good works.
Ephesians 2: 8-9 (ESV) "For by grace you have been saved through faith. And this is not your own doing; it is the gift of God, not a result of works, so that no one may boast."
The greatest blessings in your life come... 1) thru His grace and 2) your willingness to accept that grace.
V. Be Holy
Practical and positional holiness. The point is that you are holy (chosen/set apart), ACT LIKE IT
1 Cor. 6:9-11 (ESV) "Or do you not know that the unrighteous will not inherit the kingdom of God? Do not be deceived: neither the sexually immoral, nor idolaters, nor adulterers, nor men who practice homosexuality, nor thieves, nor greedy, nor drunkards, nor revilers, nor swindlers, will inherit the kingdom of God. And such were some of you. But you were washed, you were sanctified, you were justified in the name of the Lord Jesus Christ and by the Spirit of God."
Act like who you are....HOLY!
VI. Conduct yourself with (holy/reverential) fear
This is not a theophobia (a fear of God/religion) that would cause you to run from God.
This is and AWE of God
Proverbs 9:10 (ESV) "The fear of the LORD is the beginning of wisdom, and the knowledge of the Holy One is insight."
VII. Know this, Remember this, Be sure of this...
1 Peter 1:18-19 (ESV) "knowing that you were ransomed from the futile ways inherited from your forefathers, not with perishable things such a silver or gold, but with the precious blood of Christ, like that of a lamb without blemish or spot."
This is something we should never forget!
