Lydia is a model ambassador!
She traded in purple. Important, rich people wore purple and she would have had business relationships with these influential people. She was likely to have been rich from her successful business.
Lydia probably had a lot! Wealth, resources, colleagues, influence, opportunities, autonomy. These things gave her a big mission field. She was an ambassador for Christ through telling people about Jesus and through extending hospitality.
She threw open her house and her resources to the church family in Philippi. She gave the church in Philippi a base – that’s her great legacy.
