Many Christians... find themselves defeated by the most psychological weapon that Satan uses against them. This weapon has the effectiveness of a deadly missile. Its name? Low self-esteem. Satan's greatest psychological weapon is a gut level feeling of inferiority, inadequacy, and low self-worth This feeling shackles many Christians, in spite of wonderful spiritual experiences and knowledge of God's Word. Although they understand their position as sons and daughters of God, they are tied up in knots, bound by a terrible feeling inferiority, and chained to a deep sense of worthlessness.
