The Cross is where this all takes place. Jesus, fully obedient to the Father, takes upon Himself the deadly penalty for all of our sins. The sins in the past, the sins in the present, and the sins of the future. All are paid for in Christ on the cross. At the cross, Jesus becomes sin for us. And that sin is nailed to the cross! In the shedding of His holy, innocent, and perfect blood, He did what no animal sacrifice could do. He atoned for our sins, once for all.
