Blessed is the man to whom the Lord will not impute sin. – Romans 4:8

You understand that so long as Jesus was here He lay under the charge of our sins. Whilst He was in the world, His Father had made to meet upon Him the iniquity of us all. But when He died, His death discharged all the liabilities of His elect. The handwriting of ordinances that was against us was then taken away. When He went to Calvary as our Surety, the sins of all His people were His debts: He had taken them upon Himself. But when He rose from the dead in the garden He had no debts of ours: He had no longer any substitutional engagement or liability. All the debts which He had taken upon Himself as our Redeemer He had fully and completely discharged. No officer can arrest a man for debt who has none, and Christ now lives, therefore, as a justified person. And,. brethren, no officer of justice can arrest any of the people for whom Christ paid their debts. How, then, shall death have any dominion over those whose debts are all discharged? How shall they be laid in prison for whom Christ was laid in prison? How shall they suffer death, which is the penalty of sin, for whom Christ has already suffered all the penalties which justice could have demanded? Because He lives the life of one who has discharged the debts of His people, they must, in justice, live.

Jesus Christ represents all the people who are in Him, and as long as He lives, they live. He is their Covenant Head. As long as Adam stands, his race shall stand; when Adam falls, the human race falls. While, therefore, Christ lives, the Christly ones, who are in Him, live through His representation. ~ C.H. Spurgeon
