161 Paul came first to Derbe, then Lystra. He found a disciple there by the name of Timothy, son of a devout Jewish mother and Greek father. 2 Friends in Lystra and Iconium all said what a fine young man he was. 3 Paul wanted to recruit him for their mission, but first took him aside and circumcised him so he wouldn't offend the Jews who lived in those parts. They all knew that his father was Greek.

Well may the church look for much service from youthful ministers who set out in the same spirit as Timothy. But when men will submit in nothing, and oblige in nothing, the first elements of the Christian temper seem to be wanting; and there is great reason to believe that the doctrines and precepts of the gospel will not be successfully taught. The design of the decree being to set aside the ceremonial law, and its carnal ordinances, believers were confirmed in the Christian faith, because it set up a spiritual way of serving God, as suited to the nature both of God and man. Thus the church increased in numbers daily.
