Why is the intertestamental period relevant to the way Christians practice their faith today?

The intertestamental period, which spans roughly 400 years between the Old and New Testaments, is crucial for understanding the historical and cultural context of early Christianity. It includes significant developments in Jewish thought, religious practices, and the emergence of various sects, such as the Pharisees and Sadducees, which influenced Jesus' teachings. Additionally, the period saw the translation of Hebrew scriptures into Greek (the Septuagint), which shaped early Christian theology and scripture. Thus, insights from this period help Christians appreciate the roots of their faith and the socio-political environment in which Jesus and the apostles operated.
