I exhort the elders among you, as a fellow elder, and a witness of the sufferings of Christ, and who will also share in the glory that will be revealed.
He himself had participated in sufferings for Christ’s sake. "Witness" (Gr. martys; cf. Acts 3:15; Acts 10:39) does not just mean that he observed Jesus suffering, which he did. It means he shared Jesus Christ’s sufferings and bore testimony out of that experience (1 Peter 4:13). As his readers, Peter also shared the glory that God will yet reveal (1 Peter 4:14).
