How do we know Christ's victory is assured?

The assurance of Christ's victory is rooted in His resurrection and ascension to the throne of glory. After suffering for the sins of humanity, He rose from the dead, demonstrating His power over sin and death. As mentioned in the sermon, this is a fulfillment of God's plan, as He is described in Revelation 5 as the 'Lion of the tribe of Judah' who prevailed to open the book of salvation. His acceptance by the Father, as noted in Psalm 24, underscores that He is the only one who has clean hands and a pure heart, making Him worthy to stand in God's presence and to intercede for His people. Thus, Christ's victory is finalized in His divine authority and role as our Savior.
