"How are we to live our lives in light of Christ's return?"
Answer: We believe that the return of Jesus Christ is imminent, that is, His return could occur at any moment. We, with the apostle Paul, look for “the blessed hope—the glorious appearing of our great God and Savior, Jesus Christ” (Titus 2:13). Knowing that the Lord could come back today, some are tempted to stop what they are doing and just “wait” for Him.
However, there is a big difference between knowing that Jesus could return today and knowing that He will return today. Jesus said, “No one knows about that day or hour” (Matthew 24:36). The time of His coming is something God has not revealed to anyone, and so, until He calls us to Himself, we should continue serving Him. In Jesus’ parable of the ten talents, the departing king instructs his servants to “occupy till I come” (Luke 19:13 KJV).
The return of Christ is always presented in Scripture as a great motivation to action, not as a reason to cease from action. In 1 Corinthians 15:58, Paul wraps up his teaching on the rapture by saying, “Always give yourselves fully to the work of the Lord.” In 1 Thessalonians 5:6, Paul concludes a lesson on Christ’s coming with these words: “So then, let us not be like others, who are asleep, but let us be alert and self-controlled.” To retreat and “hold the fort” was never Jesus’ intention for us. Instead, we work while we can. “Night is coming, when no one can work” (John 9:4).
The apostles lived and served with the idea that Jesus could return within their lifetime; what if they had ceased from their labors and just “waited”? They would have been in disobedience to Christ’s command to “go into all the world and preach the good news to all creation” (Mark 16:15), and the gospel would not have been spread. The apostles understood that Jesus’ imminent return meant they must busy themselves with God’s work. They lived life to the fullest, as if every day were their last. We, too, should view every day as a gift and use it to glorify God.
