Well scripture guy I suggest you read the book of Hebrews. Hebrews 8:8,13; 9:15, 10:20 and 12:24 all refer to new covenant we are in and Christ is the mediator of it.
In commenting on the words of the Holy Spirit the book of Hebrews says - "In speaking of a new covenant, he makes the first one obsolete. And what is becoming obsolete and growing old is ready to vanish away." Heb 8.13
Can you post Hebrews 8:8 and tell me who the new covenant is made with?
