This sermon explores why the Bible is divided into the Old and New Testaments, showing how both parts tell one unified story of God’s plan for salvation. The Old Testament reveals the covenant with Abraham and the promise of a coming Messiah, while the New Testament fulfills that promise through Christ’s life, death, and resurrection. Together, they form a scarlet thread of redemption—from creation and fall to restoration in Christ—calling us to live in faith and await His return.
