A red heifer is integral to the Mosaic law's purification rituals, detailed in Numbers 19:1–10, and was essential for ancient Israelite worship practices. The ritual's significance continued from Moses' time through the temple period until AD 70 and will likely be required for future temple sacrifices as described in Ezekiel 41—45. The New Testament predicts a future Jewish temple that the Antichrist will desecrate (Matthew 24:15). Jesus taught that no one knows the timing of His return (Mark 13:32), and the imminent rapture of believers encourages holy living and proclaiming our faith through evangelism (John 14:1–3; 1 Thessalonians 4:13–18). Believers are called to make disciples of all nations, as commanded in Matthew 28:18–20.
Jesus taught that no one knows the day or hour of Christ's return (Mark 13:32). The next major event in biblical prophecy to take place is the rapture of believers by Jesus Christ (John 14:1–3; 1 Corinthians 15:51–58; 1 Thessalonians 4:13–18). This event can happen at any moment. The fact that other aspects of prophecy that will take place following the rapture are seen today suggests that we may be very close to the fulfillment of biblical prophecy. For the believer, this should encourage us (1 Thessalonians 4:18) as we look forward to eternity with Christ.
In addition, the any-moment return of Jesus should cause us to live holy lives and share Christ with others. As Jesus commanded His followers before leaving earth, "Go therefore and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit, teaching them to observe all that I have commanded you" (Matthew 28:19–20).
