If you have judged me to be faithful to the Lord, come and stay at my home.
Timothy was a disciple and his mother was a Jewish woman who was a believer. Timothy was well spoken of by the believers, therefore Paul wanted Timothy to accompany him. They went from town to town strengthening and growing the church daily.
The men went through the region of Phrygia and Galatia. During one of their nights of travel Paul had a vision of a man in Macedonia saying "Come over to Macedonia and help us". The men immediately tried to cross over, for they were convinced God had called them. 
The men remained in Philip'pi for a couple days. On the sabbath day they went to the gate by the river which was a place of prayer. A woman named Lydia was listening to them. When she and her household were baptized, she urged them, saying, "If you have judged me to be faithful to the Lord, come and stay at my home."
