Why do we have pastors and General overseers who just go about building their own churches in every crook and cranny. I understand everyone needs to hear the gospel. But in the great commission as we call it, before Jesus went back to heaven, he told his disciples to preach to every creature all over the world. i.e Envagelism. [Matt 28:18-20] But he never commanded them nor we to build our own churches. So where did nowadays church owners get such command from? Please, I need biblical answers.
