in the highest sense belongs to God (Isa. 6:3; Rev. 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 (Rom. 6:19, Rom. 6: 22; Eph. 1:4; Titus 1:8; 1-Pet 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-Cor 1:30; 2-Cor 7:1; Eph. 4:23, Eph. 4: 24). (See SANCTIFICATION.)
