Peter gives us a strong encouragement toward Christian holiness which is marked by separation from sin, imitation to God and permeation of this reality in every aspect of our lives. Peter points out in this passage five motivations for holy living: filiation (we are new covenant children of God who obey the Lord from a changed heart), extinction (our former life should never be brought into the present), revelation (this duty of the people of God has been written down by God in Scripture), evaluation (God evaluates our lives with objective and impartial judgment), and calculation (Christ paid the infinite price of ransom for our redemption). May the Lord help us to have the wisdom of the Word of God to daily pursue a life of holiness.

1 Peter 1:14-19
14 As obedient children, do not be conformed to the former lusts which were yours in your ignorance, 15 but like the Holy One who called you, be holy yourselves also in all your behavior; 16 because it is written, “YOU SHALL BE HOLY, FOR I AM HOLY.” 17 If you address as Father the One who impartially judges according to each one’s work, conduct yourselves in fear during the time of your stay on earth; 18 knowing that you were not redeemed with perishable things like silver or gold from your futile way of life inherited from your forefathers, 19 but with precious blood, as of a lamb unblemished and spotless, the blood of Christ.
