C.H. Spurgeon emphasizes the significance of four pivotal events in Christ's life: His birth, death, resurrection, and ascension, which collectively lead to the anticipation of His second coming. He encourages believers to reflect on these events, recognizing that each one points towards the glorious return of Jesus, who will come again in the same manner as He ascended. Spurgeon gently admonishes the disciples for their prolonged gazing into heaven, urging them instead to engage in active service and fulfill their mission on earth. He reassures them that 'this same Jesus' who ascended is alive and will return, encouraging a life of faith and action in preparation for His coming. The sermon calls for a balance between contemplation and active service, reminding believers to focus on their responsibilities while eagerly awaiting Christ's return.
