I think of Joseph and Mary, who heard what Jesus had to say and did not understand what he spoke to them. How many people reacted to Jesus in that same way? They heard his words... but they didn't grasp the importance of them, the weight of them, the impact of them?
How many of us are like that? We read the words of Jesus, and we understand the surface level meaning, but do we grasp the full impact, the full weight, the meaning they're intended to have in our lives? CS Lewis said he didn't worry about the sayings of Jesus that he didn't understand, he worried about the sayings of Jesus that he did understand, because they were the ones demanding change from him, asking much of him. I do the same thing -- I skim over some of the harder teachings, because I don't want to change. I don't always like change.
So let us let the words and teachings of Jesus sink in as we dive deeper into the Gospels. May we let the challenging teachings of Jesus sit in our hearts, treasuring them up, and seeing where God is calling us.
