� Historical & Literary Context

The Gospel of Matthew was written by Levi, the former tax collector turned disciple of Jesus, likely in the mid-to-late first century (around 60-70 AD). Writing primarily to a Jewish-Christian audience, Matthew sought to prove that Jesus is the promised Messiah, the King of Kings who fulfills the Old Testament scriptures. Matthew’s first-century readers were navigating intense social and religious pressure, caught between their ancestral Jewish traditions and their new faith in Christ. This specific verse is found in the Sermon on the Mount (Matthew 5-7), which serves as Jesus' foundational…

� A Picture of This Truth

Imagine a homeowner who buys a beautiful house in the suburbs during the winter. In the backyard stands a mature, majestic-looking apple tree. The homeowner excitedly looks forward to the autumn, imagining warm kitchens filled with the sweet aroma of homemade apple pies. But when autumn finally arrives, the tree produces apples that are small, black-spotted, and taste like vinegar. Frustrated, the homeowner tries to solve the problem superficially. They buy high-gloss wax to polish the bitter apples, spray them with sweet-scented oils, and even tie realistic plastic apples to the branches to…
