“Simeon Peter, a servant and apostle of Jesus Christ, To those who have obtained a faith of equal standing with ours by the righteousness of our God and Savior Jesus Christ” (2 Peter 1:1).
Peter address his second letter to “those who have obtained a faith of equal standing”. All who have faith in Jesus Christ as Lord and Savior are brothers and sisters of Christ and therefore of one another (Hebrews 2:11-13) though our circumstances, age and cultures differ from one another. We have all obtained faith “by the righteousness of Christ.”
We did not save ourselves.
