In our readings for Sunday, we have completed our journey through John and now move on to Mark. Our readings all point us to a comparison of the Laws given by God to Moses and how Jesus' coming into the world changed how they are applied. God gave Israel the stone tablets on which the law was written. Jesus writes the law in our hearts and our minds when we come to know Him. Israel had to enter the temple to have access to God. Jesus, His Father, God, and the Holy Spirit come into us, when we accept Him as savior, and make their home in us, making each of us their holy temple. Israel in Jesus' time thought it was okay to obey the letter of the law, keeping them outwardly, while breaking them inwardly.
Jesus calls us to a total commitment to His Law. It is not what is outside of us that makes us unclean, it is what flows our from our hearts that matters.
