How do we know Christ's victory is complete?

The completeness of Christ's victory is established through His atoning work on the cross, where He bore the sins of His people and declared, 'It is finished' (John 19:30). This signifies that all that was required for the redemption of His people has been accomplished. In Colossians 2:15, we see that Christ disarmed the powers and authorities, triumphing over them by the cross. The victory is not just symbolic; it is a definitive declaration that sin, death, and Satan have been defeated. As believers, we can rest in the assurance that our salvation is secure, and we partake in Christ’s victory over all spiritual enemies, as affirmed in Romans 8:37, where we are told we are more than conquerors through Him.
