We all know that holiness is good. Being without sin, doing what is right, finding forgiveness in God...These are all things that might flash through our minds when we think about "being holy". However, living out a life of holiness for anyone that has ever tried is often much more difficult isn't it? However, it is here that Peter gives us the best example of holiness Jesus Christ, the perfect lamb of God without blemish or defect, offered His blood as a sacrifice for our sins. This is where we find our holiness. This is where we focus our attention. This is how we can live holy lives through the spirit of Christ, the Holy Spirit, living in us.
1 Peter 13-25: Therefore, with minds that are alert and fully sober, set your hope on the grace to be brought to you when Jesus Christ is revealed at his coming. 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."Since you call on a Father who judges each person’s work impartially, live out your time as foreigners 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 ancestors, but with the precious blood of Christ, a lamb without blemish or defect. He was chosen before the creation of the world, but was revealed in these last times for your sake. Through him you believe in God, who raised him from the dead and glorified him, and so your faith and hope are in God.
Now that you have purified yourselves by obeying the truth so that you have sincere love for each other, love one another deeply, from the heart.For you have been born again, not of perishable seed, but of imperishable, through the living and enduring word of God. For,
“All people 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 endures forever.”
And this is the word that was preached to you.
