Jesus taught why it is necessary to obey his teaching, not just listen to it.

Luke 6:46-49

46 “Because people should obey what their masters tell them, ◄it is disgraceful that you say that I am your master but you do not do what I tell you!/why do you say that I am your master but you do not do what I tell you?► [RHQ] 47 Some people come to me, and hear my messages and obey them. I will tell you what they are like. 48 They are like a man who dug deep into the ground to prepare to build his house. He made sure that the foundation was on solid ground. Then when there was a flood, the water tried to wash away the house. But the river could not shake the house, because it was built {he built it} on a solid foundation. 49 But some people hear my messages but do not obey them. They are like a man who built a house on top of the ground without digging a foundation. When the river flooded, the house collapsed immediately and was completely ruined. So it is important for you to obey what I teach you.”
