Why is being ready for Christ's return important for Christians?

Christ's return is a key element in Christian eschatology, underscoring the importance of being spiritually prepared. In the parable of the ten virgins (Matthew 25:1-13), the distinction between the wise and foolish virgins highlights the necessity of being ready at all times. The wise virgins, who brought oil for their lamps, signify believers who are prepared for the bridegroom's arrival. This readiness symbolizes faith and spiritual vigilance, ensuring that we will be welcomed into eternal fellowship with Christ when He returns. The call to 'watch therefore' reflects the need for constant readiness and faithfulness.
