When Paul evangelized to the Jews, they rejected him and his message as they saw him as a heretic. When he evangelized to the Gentiles, the Gentiles received the Gospel better, but came under intense persecution from the Jews and the Law. So how could Paul evangelize without the many laws, rules, and regulations that the law (outside the Ten Commandments) carried? The truth is, he didn't need them. When Jesus was on earth, He gave us principles to live by because He lived by them. Christ met people where they were and became all things to all people, and that's exactly how Paul evangelized. And so, we need to love people where they're at so that they can see the love of Jesus, and let the power of His message, presence, and Word, grow and bring forth life from there.
