Final answer:
The author of Hebrews encourages believers to hold fast to their confession and not to forsake assembling together, emphasizing the importance of faith and community among believers.
Step-by-step explanation:
According to the author of Hebrews, in light of what Jesus has done, believers are encouraged to hold fast to their confession without forsaking assembling together. This exhortation can be found in the New Testament within the context of the letters to the early Christian communities. The book of Hebrews particularly emphasizes the importance of faith, perseverance, and community among believers, encouraging them to maintain their confession of faith and to continue to gather, support, and encourage one another in their spiritual journey, in light of Jesus's sacrifice and teachings. It provides a contrast to the idea that believers should rely on their own strength or abandon their beliefs due to challenges. Instead, the focus is on communal support, shared faith, and the hope that is found in Jesus's actions and promise of salvation.
