What does the Bible say about the power of the cross?

The cross of Christ is central to the Christian faith, signifying the power that decisively breaks the fellowship between believers and the world. This power is not derived from Christ's teachings or example but is fundamentally found in His death by crucifixion. Through the cross, believers experience deliverance from sin’s hold, making it a victorious symbol of salvation. It is essential to glory in the cross, recognizing that it is the efficient means through which God accomplishes redemption and reconciliation with Himself.
