The First Epistle of Peter was written by the apostle Peter from Rome between A.D. 64 and 67 to Christians who had fled Asia Minor. It admonishes the pilgrims to have hope and courage and to trust in the power of God.

1 Peter 2

2:5 Ye also, as lively stones, are built up a spiritual house, an holy priesthood, to offer up spiritual sacrifices, acceptable to God by Jesus Christ.
