What Does the Bible Say About Holiness — Meaning Explained

1 Peter 1:15-16 commands, 'But as he which hath called you is holy, so be ye holy in all manner of conversation; Because it is written, Be ye holy; for I am holy.' Holiness means being set apart — distinct from the world's values and dedicated to God. Leviticus repeatedly declares God's holiness as the basis for the people's conduct. Hebrews 12:14 warns, 'Follow peace with all men, and holiness, without which no man shall see the Lord.' Yet holiness isn't achieved by human effort alone — it's the work of the Holy Spirit (2 Thessalonians 2:13). Romans 12:1-2 calls for presenting our bodies as 'living sacrifice, holy, acceptable unto God.' Holiness encompasses moral purity, separation from sin, devotion to God, and transformation into Christ's image. It is both a position (declared holy in Christ) and a process (growing in practical holiness).
