How do we know Christ's return is important for Christians?

The return of Christ is a pivotal doctrine for Christians as it symbolizes the completion of God's redemptive work. Matthew 24 describes His return as sudden and visible, akin to lightning lighting up the sky, eliminating fears of a secret rapture. For believers, this event is the culmination of hope, where they will be gathered to Christ for eternal worship, free from suffering and sin. The anticipation of Christ's return encourages Christians to live righteously and maintain faith in God's sovereign plan.
