Acts 16-18

Chapter 16 begins with Paul's introduction to Timothy in Lystra. This young man was a believer but had been raised as a Greek. Paul wanted Timothy to accompany him in his ministry. Verses 3 and 4 present two actions that on the surface appear contrdictory; Paul persuaded Timothy to be circumcised and the proclaimed the decision of the leaders in Jerusalem that circumcision and following the Law was not a necessary part of being a Christian. I wonder what lesson Paul wished to present?
