How do we know that Jesus fulfilled His mission?

The assurance of Jesus fulfilling His mission lies in His resurrection and the divine confirmation of His work. According to the scriptures, God raised Christ from the dead, and He is now seated at the right hand of the Father as our justification. His successful completion of the redemptive work is evidenced by His authority over sin and death. Jesus was not merely a martyr; He was the divine Son who accomplished the task set before Him by the Father, demonstrating that His sacrificial death was indeed effective for the salvation of His elect.
