In the present paragraph Peter works out the manner in which Christians ought to respond to the salvation they have received as described in 1 Peter 1:3–12. Specifically, since Christians are adopted to be children of God, they are to reflect what their heavenly Father is like; “like Father, like son.”
13 C'est pourquoi, ceignez les reins de votre entendement, soyez sobres, et ayez une entière espérance dans la grâce qui vous sera apportée, lorsque Jésus-Christ apparaîtra.
