C.H. Spurgeon preaches on the significance of Christ's ascension, emphasizing that while His physical presence is no longer with us, it is for our benefit that He ascended to the Father. He explains that Jesus' departure allows the Holy Spirit to come and empowers believers to live by faith rather than sight. Spurgeon highlights the triumph of Christ's ascension over sin, death, and Satan, and the gifts He bestows upon the church, including pastors and evangelists. He encourages believers to embrace their heavenly citizenship and to actively participate in the ministry of the church, while also extending a call to sinners to seek repentance and salvation through the ascended Christ.
