Nobody said it would be easy. It is a difficult road, hard to follow and it takes a lot of courage.
I came not to bring peace but a sword. Jesus teaching that his gospel of repentance and Holiness and truth would cause great division among people and families. As some would recognize him as God incarnate and follow his teachings and others would reject him. Jesus is the prince of peace, and gives His peace to those who accept him and keep his commands, but in the world expect division, discord and persecution from those who reject Him.
