What does the Bible Say About Contentment?

I am learning a lot about contentment. Here are some great thoughts on the subject:

“The truly godly person is not interested in becoming rich. He possesses inner resources which furnish riches far beyond that which earth can offer.” William Hendriksen

“Contentment is one of the most distinguishing traits of the godly person because a godly person has his heart focused on God rather than on possessions or position or power.” Jerry Bridges, The Practice of Godliness ; pg. 85

“Godliness with contentment is great gain.” 1 Timothy 6:6

“A godly person has found what the greedy of envious or discontented person always searches for and never finds. He ha found satisfaction and rest in his soul.” Jerry Bridges

“Discontentment it the questioning of  God’s goodness.” Jerry Bridges
