Holiness: in the highest sense belongs to God (Isaiah 6:3; Revelation 15:4), and to Christians as consecrated to God's service, and in so far as they are conformed in all things to the will of God (Romans 6:19,22; Ephesians 1:4; Titus 1:8; 1 Peter 1:15). Personal holiness is a work of gradual development. It is carried on under many hindrances, hence the frequent admonitions to watchfulness, prayer, and perseverance (1 Corinthians 1:30; 2 Corinthians 7:1; Ephesians 4:23,24). (See SANCTIFICATION.)
