The biblical concept of holy means to be set apart for God's purpose, namely, to reflect His character and righteousness. Mentioned nearly 900 times in Scripture, holiness consists of not merely moral behavior, but a complete spiritual transformation through God's Holy Spirit, as exemplified by keeping His seventh day Sabbath, sanctified as a sign of God's covenant with His called-out people (Ezekiel 20:12). We need to emulate examples like Moses, Joshua, and Abraham, who was chosen, set apart, and faithful, becoming a "friend of God" (James 2:23, Isaiah 41:8). Ancient Israel, similarly chosen as a holy nation to represent God (Deuteronomy 14:2, Exodus 19:15),sadly failed miserably to internalize this covenant. Today, the Israel of God (Galatians 6:16), God's church, is called to be a chosen generation and holy nation and to live righteously, reflecting God's love and character. Sanctification is a lifelong process requiring obedience, faith, and readiness for spiritual challenges (I Peter 1:13-15). Thankfully, Christ's life and death enabled this level of holiness. We must continue to grow in godly virtues, remaining steadfast.
