Holiness

Holiness is the quality of being set apart for God and belonging to him, and, flowing from that, a life made morally pure and devoted to him. The Hebrew and Greek words commonly translated "holy" carry the root sense of separation or consecration — something marked off from ordinary use because it belongs to God. Scripture applies the word first to God's own character and then to a people he claims: 1 Peter 2:9 calls believers "a holy nation, a people for God's own possession," and Ephesians 1:4 says he chose us in Christ "before the foundation of the world, that we would be holy and without defect before him in love."

The text also presents holiness as a moral reshaping of the person, not merely a status. Ephesians 4:24 speaks of putting on "the new man, who in the likeness of God has been created in righteousness and holiness of truth," and Colossians 3:10 describes that new self as "being renewed in knowledge after the image of its Creator." Romans 12:2 ties the same transformation to a renewed mind that proves "what is the good, well-pleasing, and perfect will of God." The practical edge of this appears in 2 Timothy 2:19, where naming the Lord's name is joined to the command, "Let every one who names the name of the Lord depart from unrighteousness," and in James 3:17, where the wisdom from above is "first pure, then peaceful, gentle, reasonable, full of mercy and good fruits."

Scripture describes the source of holiness as God's own action rather than human effort alone. Galatians 5:22 lists the fruit of the Spirit, beginning with love, joy, and peace; 1 John 1:7 grounds cleansing in "the blood of Jesus Christ his Son"; and 1 Peter 2:24 says Christ bore our sins "that we, having died to sins, might live to righteousness." John 4:14 pictures the same gift as inward and ongoing — water that "will become in him a well of water springing up to eternal life."

Christian traditions differ over how to describe this. Many Wesleyan and Holiness churches teach entire sanctification as a distinct work of grace subsequent to conversion, while Reformed and much Lutheran theology stress holiness as both a definitive setting apart in Christ and a gradual growth that remains incomplete in this life; Eastern Orthodox teaching commonly frames the goal as theosis, a real participation in God's life. One way of reading the biblical material is that these accounts weight differently the same two notes Scripture keeps together — holiness given in Christ and holiness worked out in a renewed life.
