King James Bible Dictionary

A state of mind in which one's desires are confined to his lot whatever it may be (1 Timothy 6:6; 2 Corinthians 9:8). It is opposed to envy (James 3:16), avarice (Hebrews 13:5), ambition (Proverbs 13:10), anxiety (Matthew 6:25, 34), and repining (1 Corinthians 10:10). It arises from the inward disposition, and is the offspring of humility, and of an intelligent consideration of the rectitude and benignity of divine providence (Psalms 96:1, 2; 145), the greatness of the divine promises (2 Peter 1:4), and our own unworthiness (Genesis 32:10); as well as from the view the gospel opens up to us of rest and peace hereafter (Romans 5:2).
