This chapter emphasizes that what truly matters is our response to Jesus. Jesus heals the servant of a non-Jew, so whether or not one is Jewish doesn’t matter. Jesus raises someone from the dead, so the severity of the problem doesn’t matter. He forgives a sinful woman, so how sinful someone is doesn’t matter. In fact, He says more sin makes a person more thankful. He responds to John the Baptist’s questions, so it was even important for a great prophet to accept Jesus.
The same is true today. Our acceptance of Jesus is the starting point of a relationship with God. Nothing in our background can prevent us from entering a relationship with God through trusting Jesus, and nothing can allow us to have a relationship with God in any other way.
