That's according to Gareth and Ali Gilkerson, the husband and wife duo who are founding members of the popular worship group Rend Collective. In this in depth interview with Premier Christianity's Sam Hailes, the couple talk about their decision to preach the Gospel at every gig, why Covid-19 has affected the band's finances and how criticism and online trolling hasn't dampened their passion for church unity.
