Holiness means being set apart for God's purposes, reflecting His pure character, and growing in moral and spiritual purity through the Holy Spirit.
"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." — 1 Peter 1:15-16 (KJV)
The Biblical Context
God's fundamental command is 'Be ye holy; for I am holy' (1 Peter 1:16, quoting Leviticus 11:44). Holiness has two aspects: positional (believers are declared holy through Christ's sacrifice, Hebrews 10:10) and practical (believers actively pursue holy living, Hebrews 12:14). The Hebrew word 'qadosh' means 'set apart' or 'distinct.' God is supremely holy (Isaiah 6:3), and He calls His people to reflect His character. Practical holiness involves fleeing sin, renewing the mind (Romans 12:2), walking in the Spirit (Galatians 5:16), and pursuing righteousness. Holiness is not about perfection but direction—progressive transformation into Christ's likeness. It is not joyless restriction but joyful freedom: 'where the Spirit of the Lord is, there is liberty' (2 Corinthians 3:17).

Supporting Passages
"Follow peace with all men, and holiness, without which no man shall see the Lord."
"Having therefore these promises, dearly beloved, let us cleanse ourselves from all filthiness of the flesh and spirit, perfecting holiness in the fear of God."
