Why is the concept of Christ's kingdom important for Christians?

Understanding Christ’s kingdom is crucial for Christians because it is the fulfillment of God's redemptive plan initiated at creation. The preaching of the kingdom represents the reign of Christ where sin and death are defeated, offering eternal life to believers. In Revelation, the vision of the Lamb opening the seals emphasizes that His kingdom will be established despite opposition from the kingdom of Satan. This hope of eternal life and belonging to the kingdom reassures Christians that they are part of a divine plan, motivating them to live righteously and witness to others about the gospel.
