Christians must not be identified with sinful attitudes or lifestyles. They should not fellowship so-called believers who continually indulge in sinful activities. They are not to become unequally yoked with unbelievers, such as by marriage. They must resolve internal disputes according to the procedure given by Christ, not by suits in civil court. Christians must maturely regulate amusements, music, sports, and games, avoiding worldly atmospheres and appearances.
Some amusements are inherently worldly, such as gambling, dancing, hard rock music, and the occult.
In sum, holiness means to imitate Christ, to be Christ-like. Holiness is an integral part of the salvation of the whole man from sin's power and effects. The life of holiness fulfills God's original intention and design for humanity. Holiness is the essence of the Christian life.
