The anticipation of Christ's return is a central tenet of Christian eschatology, deeply rooted in the teachings of the New Testament. This expectation shapes the lives of believers, influencing their conduct, priorities, and worldview. The doctrine of the Second Coming is not merely a future hope but a present reality that calls for vigilance, holiness, and active engagement in the mission of the Church.

Biblical Foundation

The New Testament is replete with references to the return of Jesus Christ. In the Gospels, Jesus Himself speaks of His return, urging His followers to remain watchful. In Matthew 24:42 , Jesus instructs, "Therefore keep watch, because you do not know the day on which your Lord will come." This call to vigilance is echoed throughout the epistles, where the apostles encourage believers to live in readiness for the Lord's return.

The Apostle Paul, in his letters, frequently addresses the theme of Christ's return. In 1 Thessalonians 4:16-17 , he writes, "For the Lord Himself will descend from heaven with a loud command, with the voice of an archangel, and with the trumpet of God, and the dead in Christ will be the first to rise. After that, we who are alive and remain will be caught up together with them in the clouds to meet the Lord in the air. And so we will always be with the Lord." This passage not only affirms the certainty of Christ's return but also provides comfort and hope to believers.

Moral and Spiritual Implications

Living in expectation of Christ's return has profound moral and spiritual implications. The Apostle Peter exhorts believers to pursue holiness and godliness in light of the coming day of the Lord. In 2 Peter 3:11-12 , he asks, "Since everything will be dissolved in this way, what kind of people ought you to be? You ought to conduct yourselves in holiness and godliness as you anticipate and hasten the coming of the day of God."

This anticipation calls for a life marked by purity, as the Apostle John notes in 1 John 3:2-3 : "Beloved, we are now children of God, and what we will be has not yet been revealed. We know that when Christ appears, we will be like Him, for we will see Him as He is. And everyone who has this hope in Him purifies himself, just as He is pure."

Watchfulness and Readiness

The expectation of Christ's return demands watchfulness and readiness. Jesus' parables, such as the Parable of the Ten Virgins (Matthew 25:1-13), emphasize the importance of being prepared. The wise virgins, who kept their lamps filled with oil, represent those who live in constant readiness for the bridegroom's arrival. This readiness is not passive but involves active engagement in the work of the Kingdom.

The Apostle Paul, in Romans 13:11-12 , urges believers to awaken from spiritual slumber: "And do this, understanding the occasion. The hour has come for you to wake up from your slumber, for our salvation is nearer now than when we first believed. The night is nearly over; the day has drawn near. So let us lay aside the deeds of darkness and put on the armor of light."

Hope and Encouragement

The expectation of Christ's return is a source of hope and encouragement for believers. It assures them that the present world, with its suffering and injustice, is not the final reality. The promise of Christ's return offers a future where God will establish His perfect justice and peace. In Titus 2:13 , Paul describes this hope as "the blessed hope and glorious appearance of our great God and Savior, Jesus Christ."

This hope sustains believers through trials and tribulations, providing a perspective that transcends temporal circumstances. It encourages perseverance and faithfulness, as seen in Hebrews 10:23-25 : "Let us hold resolutely to the hope we profess, for He who promised is faithful. And let us consider how to spur one another on to love and good deeds. Let us not neglect meeting together, as some have made a habit, but let us encourage one another, and all the more as you see the Day approaching."

Mission and Evangelism

The anticipation of Christ's return also fuels the mission and evangelistic efforts of the Church. Believers are called to proclaim the Gospel to all nations, as part of preparing the world for the coming of the King. In Matthew 24:14 , Jesus declares, "And this gospel of the kingdom will be preached in all the world as a testimony to all nations, and then the end will come."

This mission is urgent, as the timing of Christ's return is unknown. The Apostle Peter, in 2 Peter 3:9 , reminds believers of God's patience, "The Lord is not slow to fulfill His promise as some understand slowness, but is patient with you, not wanting anyone to perish but everyone to come to repentance." This underscores the importance of evangelism and discipleship in the time leading up to Christ's return.
