� Historical & Literary Context

The Gospel of Matthew was written by Matthew, also known as Levi, a former tax collector who became one of Jesus’ twelve disciples (Matthew 9:9). Writing primarily to a Jewish-Christian audience in the first century, Matthew’s central goal is to demonstrate that Jesus is the promised Messiah, the King from the line of David who fulfills the Old Testament scriptures (Matthew 1:1).

The Trap of Human Tradition: The Pharisees elevated their own customs to the level of divine law, showing how easily religious traditions can distract us from God's actual commands (Matthew 15:3). We must always test our habits and expectations against the clear teaching of Scripture. The Courage of Truth: Jesus did not water down…

Imagine a beautiful, historic home in a quiet suburban neighborhood. From the street, it looks absolutely stunning.
