Andrew Bonar emphasizes the significance of singing in the face of suffering, highlighting that Jesus sang a hymn with His disciples just before His impending crucifixion, demonstrating His humanity and the power of song in times of distress. He reflects on the tradition of singing Psalms, particularly Psalm 118, during the Passover, and encourages believers to sing unselfishly, even amidst trials, as a means of finding strength and joy. Bonar reminds us that Christ's last moments were filled with song, and that we too should maintain a cheerful spirit in the face of adversity, trusting in God's unwavering love. He concludes with the hope of a future where Christ will lead the redeemed in a song of praise, celebrating completed redemption.
