In Christianity, it is said that Jesus provides salvation. Salvation from what, though? 'Salvation from your sins' seems to be a common answer, but that still sounds vague. It differs from Judaism and Islam in that one can go directly to G-d in repentence. Where did this Christian concept of salvation come from, and from what, exactly is this salvation? Can a Christian go directly to 'God the Father' and ask forgiveness? If not, why not? It seems odd to me that a middleman such as Jesus is needed.
