what does the bible say?
The Bible teaches that God’s people are to be separate and distinct from the world. The Old and New Testaments show that true believers are to lead lives that glorify God. In the Old Testament, God chose the Israelites to be a light to other nations (Deuteronomy 4:5–7; Psalm 67:1–2; Isaiah 49:6). The Mosaic Law was meant as a way to set apart Israel as a holy nation (Exodus 19:5–6; Leviticus 20:26). However, the Israelites repeatedly fell into sin, even worshiping idols (Judges 2:11–12; Nehemiah 9:26). The New Testament records Christ coming in human form to deliver the Jews from the burden of the law (Galatians 3:24–25) and cover all those who believe in Him with His righteousness (2 Corinthians 5:21; Philippians 3:9). Scripture teaches that those who believe in Christ as Messiah are no longer slaves to sin but can now lead lives that testify to Christ (Romans 6:6–7; 2 Corinthians 5:17; Galatians 2:20; 5:22–24). Through word and deed, believers should be a living testimony to Jesus (Matthew 5:16; Ephesians 5:1–2; 1 John 2:6).
