God calls His people to live lives marked by holiness and righteousness—not as a condition of salvation, but as a reflection of their relationship with Him—and when believers persist in defiance of His revealed will, divine discipline may follow, including, in some cases, physical death as a solemn expression of His holiness and justice, particularly during critical moments of redemptive history (1 Pet 1:15–16; Rom 6:13; 2 Cor 7:1).
