The Book of I Peter looks at the persecution of Christians.
It was written from Rome by the apostle Peter in roughly 65 AD, shortly after the great fire in Rome which had devastated the city. Christians were being persecuted at the time, and a false rumour had started which blamed them for the fire. Amidst all this hostility, Peter wrote this letter to Christians throughout the Empire, showing them how to withstand these dangerous times.
Peter tells his readers not to lose hope. They must not become resentful of their persecutors, but rather live obediently so as to be good witnesses for God. They should trust in Christ and look for His return.
I Peter 3:3-4
"Whose adorning let it not be that outward adorning of plaiting the hair, and of wearing of gold, or of putting on of apparel; but let it be the hidden man of the heart, in that which is not corruptible, even the ornament of a meek and quiet spirit, which is in the sight of God of great price"
