How do we know that Jesus is stronger than Satan?

The assurance of Christ's strength over Satan is a pivotal doctrine in Reformed theology. This is vividly depicted in Matthew 12:29, where Jesus illustrates His authority: 'Or else how can one enter into a strong man's house and spoil his goods, except he first bind the strong man?' This metaphor indicates that Jesus, as the stronger one, has bound Satan and spoiled his house, which leads to the redemption of those held captive by sin. Believers can find comfort and hope in knowing that Christ's victory over sin and death is not merely a promise but a reality, as seen in 1 John 3:8, which states that 'the Son of God was manifested, that he might destroy the works of the devil.' The reality of Christ's victory provides believers the assurance to stand firm against the devil's schemes.
