How do we know Godliness with contentment is true?

We know that 'godliness with contentment is great gain' due to its affirmation in Scripture, specifically in 1 Timothy 6:6. This teaching contrasts sharply with worldly views of success, showing that true wealth comes from a godly life characterized by contentment in God's providence. Believers are reminded that they brought nothing into this world and can take nothing out of it (1 Timothy 6:7). This reality leads to an understanding that lasting fulfillment is found not in material possessions but in the sufficiency of Christ and the grace He provides. The testimony of believers throughout history also supports this truth as they find joy and peace despite their earthly circumstances.
