Let them share their joy with you . . . Remind yourself that net worth and personal value are not related to each other. Avoid impulse buying. Take time to determine whether you really need something and whether or not your resources may not be able to be invested in more eternal investments. Don't measure yourselves by others.
Different people have different needs.
What may be a necessity for someone else may be an unnecessary extravagance for you. When it all comes down to it, contentment is trusting God. It is trusting that God will provide what we need and that He knows what we need better than we do. It is resting in the confidence that our joy and our position in Christ has absolutely nothing to do with what we have or have been given. These things are incidentals.
