The One Man's Obligation Leads to Justification and Life for All Men

Gaston wanted to say with Roman 5 that each one of us is either in born in Adam or reborn in Christ and our fate depends on the head of the body we're in. He's saying it's the fate of the one everyone else's fate is rolled up into it. Gaston says we all were in that one man when we all were that one manWe're all in Adam we need to be reborn from and in Christ can I just give you one other verse that that may help on this come with me to Hebrews 7 there are loads of us we could do go to for this but I'm just gonna jump straight out of this one Hebrew something.
