Why is the belief in Christ's second coming important for Christians?

Belief in the second coming of Christ is foundational to the Christian faith as it encapsulates the promise of final redemption and restoration for believers. Revelation 22:20 reflects the assurance that Christ will return quickly, bringing with Him the fulfillment of prophecies about gathering His people and establishing His eternal kingdom. This hope is critical as it serves to encourage Christians to live in expectation and faith, even amidst trials and tribulations. The New Testament reinforces this doctrine through various authors who affirm that Christ will indeed return for those who await Him. The second coming is not only a promise of judgment for the world but also a source of great comfort for believers, assuring them that all injustices will be righted and believers will be gathered to partake in eternal communion with Christ.
