After spending some time there, he left and traveled through the district of Galatia, [and] then through Phrygia, strengthening [spiritually] all the disciples [along the way].

And when he desired to travel over into Achaia, he was encouraged [to do so] by the brothers, who wrote to the disciples [in Achaia and urged them] to welcome him. When he arrived [in Achaia] he was a great help to those who had become believers through the unearned favor of God. [Note: An alternate meaning is, "he was a great help, through God's unearned favor on him to those who had become believers"].
