Romans 5:18-21

18 Therefore, as one trespass led to condemnation for all men, so one act of righteousness leads to justification and life for all men. 19 For as by the one man's disobedience the many were made sinners, so by the one man's obedience the many will be made righteous. 20 Now the law came in to increase the trespass, but where sin increased, grace abounded all the more, 21 so that, as sin reigned in death, grace also might reign through righteousness leading to eternal life through Jesus Christ our Lord.

"With Adam is bound up the entrance of sin into the world and the reign of sin, condemnation, and death. With Christ is bound up the entrance of righteousness and the reign of grace, righteousness, justification, life. These two heads of humanity and the two parallel yet opposing complexes bound up with them are the pivots on which the history of humanity turns. God's government of the race can be interpreted only in terms of these two headships and of the respective complexes which the heads set in operation. These are the pivots of redemptive revelation, the first as making redemption necessary, the second as accomplishing and securing redemption." (Murray, John.
