John Nelson Darby emphasizes the integral role of the Lord's coming in Christian faith, asserting that it is woven into the very fabric of Christian thought. He explains that while Christ was rejected by the world, His return is essential for the completion of Christianity, as it fulfills the hope of redemption and the promise of being with Him. Darby illustrates this through various biblical references, highlighting the importance of waiting for Christ's return as a defining characteristic of a believer's life. He encourages Christians to remain vigilant and prepared, as the anticipation of Christ's coming should shape their actions and affections. Ultimately, Darby reassures that the joy of being with Christ is the ultimate hope for believers.
