Lydia was a merchant from Asia Minor, while she was staying with her family in Philippi, Macedonia, Greece.
One day near the river of the Zygote she went to hear the Apostle Paul preach the word of God and immediately excited by the words of the Apostle she asked to be baptized a Christian. Thus Lydia was the first Greek and European Christian!
