Sometimes contentment means:
1) Learning to be happy with less. A hard-charging executive decided to spend a few days in a monastery. 'I hope your stay is a blessed one,' said the monk who showed him to his cell. 'If you need anything let us know. We'll teach you how to live without it.' Happiness isn't getting what you want, it's enjoying what God's given you. Paul said he had learned to be content, '...whether well fed or hungry, whether living in plenty or want. I can do everything through him who gives me strength.' (Philippians 4:12-13 NIV)
2) Reminding yourself things could be worse. Snoopy was lying in his dog house one Thanksgiving Day, mumbling about being stuck with dog food while all those humans got to be inside with the turkey and gravy and pumpkin pie. 'Of course, it could have been worse,' he finally reflected, 'I could have been born a turkey.' Reminding yourself 'It could be worse' can be a powerful developer of contentment.
3) Understanding that what you seek is spiritual, not material. Paul says to beware of '...greed, which is idolatry' (Colossians 3:5 NIV). Our problem isn't just that we want more, it's that the condition which underlies all our wanting is that we really want God. As Augustine said, 'Our souls will never rest, until they rest in Thee.' Why would God let us feel at home, when this world is not our home? Our dissatisfaction, if we let it, can sharpen our spiritual hunger and cause us to pray, 'your kingdom come, your will be done on earth as it is in heaven' (Matthew 6:10 NIV).
