Bishop Mack has traveled on three continents.  His global work began with international missions trips to Haiti and Israel.  Because of his sense of discernment and spiritual perspicacity, he is considered a churchologist.  He is called upon by churches and organizations to develop strategies and formulate ministries that impact the internal and external climate of the entity.  Additionally, he analyzes corporate culture and imparts guidance spirituality in the workplace and consultation in cultural awareness and diversity.  His insight and skills have also been used at Tyson Foods, working with chaplains and ministers from more than 120 countries, American Express, Western Carolina University, Elon College, Wake Forest University, Harvard University, Winston-Salem Urban League, and the NAACP.

Bishop Mack has envisioned and implemented innovative methods of evangelism to spread the gospel of Jesus Christ.  Among his pioneering outreach methodology are programs that are reaching the non-church goer in a contemporary culture. Included but not limited to are: the Corner 2 Corner Drug Dealers Conference (C2C) where hundreds of drug dealers have been galvanized to enhance their knowledge of God, self and society; the Gospel Ice Cream truck reaching young children; First Friday concert series to reach young adults and provide an alternative to night clubs; and the Youth Character Football League with an emphasis on providing youth with a positive athletic experience, while addressing prevalent social issues.
