"Be loving and humble" covers it all. This means that any holier-than-thou attitude is out. Feeling self-righteous is out. Look up to rather than down on the person you wish to convert. The great saints always consider themselves to be the worst sinners before God. Never think that you are doing some great work or will receive recognition from God; it's the Lord doing the work through you. You do it for the glory of God alone. Be patient to avoid rushing ahead of the Holy Spirit. Leave all outcome to the Lord ~ trust is requisite. And by the way, example is better than talk. Last but not least, pray hard from the heart for the other person (as well as for yourself). St. Monica prayed and fasted for 17 years before her son St. Augustine was converted.
