What took place in Christ's death on the cross? The short answer is this: "Christ died for our sins" (1 Cor, 15:. Christ's death for our sin must be understood in two braoad  ways: First, when Jesus was nailed to the cross, the Father charged to Him all of our sin (2 Cor. 5:21) and judged the full penalty of our sin in Jesus as He died (Col. 2:14), Second, Jesus conquered the power of Satan, darkness, and death as He died for our sin (Col. 2:15; Heb. 2:14) thus establishing His supreme authority and power over everthing in creation (Eph. 1:20-23). To summarize, in His death on the cross Jesus fully paid the penalty for our sin, and He totally defeated the power of sin.

Jesus' subsequent resurrection from the dead was not just a nice ending to the story but rather necessary evidence that His death for sin rally worked (1 Cor. ​ 15:17). The penalty of sin is death, and the greatest power that sin has over us is death. But since the penalty of sin is death, and since Christ paid the penalty of sin fully by His death on the cross, His resurrection from the dead demonstrated that the penalty had been paid in full. And since the greatest power of sin is death, and since Christ conquered all of sin

s power in His death on the cross, His resurrection also demonstrated that the complete power of sin had been defeated as He arose victorious from the grave.
