Peter asks them to put away malice, deceit, envy and slander, and like newborn infants to long for pure spiritual milk so as to grow into salvation. As they come to Christ, the living stone rejected by men but chosen and precious to God, believers are built up as a spiritual house and a holy priesthood to offer spiritual sacrifices through Jesus Christ. For those who believe the stone is precious; for those who do not, it is a stone of stumbling.
Believers are a chosen race, a royal priesthood, a holy nation and a people for God's own possession, to proclaim the excellencies of the one who called them out of darkness into his light; once they were not a people, but now they are God's people. As sojourners and exiles they must abstain from the passions of the flesh and keep their conduct honorable among the Gentiles, so that, seeing their good deeds, those people may glorify God.
They must submit to every human institution, to the emperor and governors, living as free people who are servants of God, honoring everyone, loving the brotherhood and fearing God. Servants must submit to their masters with respect, even the unjust, for it is gracious in God's sight to endure while suffering unjustly.
To this they were called, because Christ suffered for them and left an example. He committed no sin, did not revile in return and entrusted himself to him who judges justly. He himself bore our sins in his body on the tree, that we might die to sin and live for righteousness; by his wounds they were healed. They were straying sheep, but have returned to the Shepherd and Overseer of their souls.
