“To the weak I became weak, to win the weak. I have become all things to all men so that by all possible means I might save some.”
This is Paul’s version of “when in Rome do as the Romans do”. Paul was starting a movement, a religious revolution, and he needed to sign up as many soldiers as possible. Paul was uniting God’s army and today we need to do the same.
Paul won people over by saying their traditions, hairstyle, dress, eating habits were okay. Paul won them with Christs’ love and new that once embraced by the Holy Spirit the end product would realize that discrimination was wrong. However , Paul realized that if their traditions were sinful in the eyes of God the Holy Spirit would convict them, forgive them and make them new.
