it is God’s will that you should be holy: Christian ethics focus on doing God's will, not on philosophical ideas about virtue (Romans 12:1–2; Ephesians 6:6; Hebrews 10:36; 13:20–21). Holiness affects every part of a person's life (1 Thessalonians 4:4, 7; 5:23). Here, it means restraint from sexual sin (Greek porneia, meaning any sexual union or activity outside marriage).
