The believer needs to understand the sin/sins that the death of Christ; had in it the past, present, and future sins of the world. The sin nature was crucified in Christ, all in Adam dead, 2 Cor. 5:14
14 For the love of Christ constraineth us; because we thus judge, that if one died for all, then were all dead:
The cup Jesus drank from had in it everything the Father required to reconcile the world back to himself.
When John the Baptist saw Jesus coming he spun around and said "behold the lamb of God that taketh away the sin of the world," the sin of the world being singular, the sin nature.
As someone mentioned we need to divide the scriptures that describe sins of the flesh or when it is speaking about the sin nature.
One separated humanity from God, the other is a mind issue.
For the believer it is mind given to body that constitutes flesh.
