How do we know that Christ's victory is assured?

The assurance of Christ's victory comes from His completed work of salvation on the cross, where He declared, 'It is finished.' This victory is affirmed by His resurrection and the establishment of His eternal kingdom. In Revelation, we see that Christ’s authority extends over all creation, including His church, which He has promised will prevail against all opposition. Romans 8 beautifully encapsulates this assurance, stating that nothing can separate us from the love of God in Christ, confirming that all the elect will ultimately be saved and gathered unto Him.
