God calls us to be holy in “all our conduct” (1 Pet 1:15), which includes not only our relationship to God but also holiness in all other relationships: within the church (2:1; 4:8–12), with unbelievers (2:9–12; 3:13–17; 4:12–19), with the government (2:13–17), within marriage (3:1–7), and between elders and the church (5:1–5). Let us give the utmost attention to this highest of callings.
