How do we know that Jesus has achieved victory over sin and death?

The victory of Jesus over sin and death is established by His resurrection from the dead, as the scripture proclaims that Christ was raised on the third day (1 Corinthians 15:4). This act of rising from the grave signifies not only His triumph over physical death but also His conquest over sin and Satan, illustrated in the sermon through the story of David and Saul. The victory is emphasized in Romans 8:37, where it states that 'in all these things we are more than conquerors through Him that loved us.' Furthermore, Christ's ascension to the throne demonstrates His position as King and intercessor for His people, where He reigns above all powers and principalities (Ephesians 1:20-22). His completed work underscores that our justification and freedom from sin rely not on our actions but entirely on His victorious sacrifice.
