In a 25-minute sermon at the Tabernacle Baptist Church in Wilson, former Congressman Mark Walker looks right at home. Walker is a preacher and a preacher’s son. His sermon is faith-based, not political. He asks congregants to turn to Matthew 16:24-25: Then Jesus said to his disciples, “Whoever wants to be my disciple must deny themselves and take up their cross and follow me. For whoever wants to save their life will lose it, but whoever loses their life for me will find it.” “Many times, in politics and in the church, we are content with only making an argument, and not making a difference,” preached Walker, who says God has called us to sacrifice and work to spread the gospel and help our fellow man in a way that reflects a Christ-like life.
