As far as conversion, I just felt that they would convert themselves based on their response to "the truth."
*** w02 4/1 p. 12 par. 13 Why Be Baptized? ***Conversion is a voluntary act performed freely by one who has made a wholehearted decision to follow Christ Jesus. Such individuals reject their former wrong course and determine to do what is right in God’s sight. In the Scriptures, Hebrew and Greek verbs pertaining to conversion have the sense of turning back, turning around. This action denotes a turning to God from a wrong way. (1 Kings 8:33, 34) Conversion calls for "works that befit repentance." (Acts 26:20) It requires that we abandon false worship, act in harmony with God’s commandments, and render exclusive devotion to Jehovah. (Deuteronomy 30:2, 8-10; 1 Samuel 7:3) Conversion results in changes in our thinking, objectives, and disposition. (Ezekiel 18:31) We "turn around" as ungodly traits are replaced by the new personality.—Acts 3:19; Ephesians 4:20-24; Colossians 3:5-14.
