You love him even though you have never seen him. Though you do not see him, you trust him; and even now you are happy with a glorious, inexpressible joy.
Your reward for trusting him will be the salvation of your souls.
This salvation was something the prophets wanted to know more about. They prophesied about this gracious salvation prepared for you, even though they had many questions as to what it all could mean.
They wondered what the Spirit of Christ within them was talking about when he told them in advance about Christ's suffering and his great glory afterward. They wondered when and to whom all this would happen.
They were told that these things would not happen during their lifetime, but many years later, during yours. And now this Good News has been announced by those who preached to you 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.
So think clearly and exercise self-control. Look forward to the special blessings that will come to you at the return of Jesus Christ.
Obey God because you are his children. Don't slip back into your old ways of doing evil; you didn't know any better then.
But now you must be holy in everything you do, just as God -- who chose you to be his children -- is holy.
For he himself has said, "You must be holy because I am holy."
References for 1 Peter 1:16
And remember that the heavenly Father to whom you pray has no favorites when he judges. He will judge or reward you according to what you do. So you must live in reverent fear of him during your time as foreigners here on earth.
For you know that God paid a ransom to save you from the empty life you inherited from your ancestors. And the ransom he paid was not mere gold or silver.
