If You Don’t Speak Up Against Sin In The Church, That Sin Will Grow And Destroy The Church

3 John 1:9-10

9I wrote to the church, but Diotrephes, who loves to be first, will not welcome us. 10So when I come, I will call attention to what he is doing, spreading malicious nonsense about us. Not satisfied with that, he even refuses to welcome other believers. He also stops those who want to do so and puts them out of the church.
