In the Gospel Paul was a missionary, there to spread the word of the Lord. He adapted himself to empathize with all people. He lived by example; therefore brought others to Him. By bringing himself to understand others and be what they were he helped meet them at their level, without ever letting his standards below what they should be. I believe an influential tool that Paul used was seeing others and meeting with them in likeness. He would have had to be a very nonjudgmental person to get to know and meet with so many others.
