So in light of the blessedness of non imputation the Elect of God were never legally responsible for their sins because Christ was as their Surety Heb 7:22
22 [FONT=&]By so much was Jesus made a surety of a better testament.
And what Testament or Covenant is that ? And when was He made the Surety of it ?[/FONT]
That is
The Everlasting Covenant:
Heb. 13:20 Now the God of peace, that brought again from the dead our Lord Jesus, that great shepherd of the sheep, through the blood of the everlasting covenant,
He was made Surety of the Covenant from Everlasting:
Prov. 8:22-23
22 The LORD possessed me in the beginning of his way, before his works of old.
23 I was set up from everlasting, from the beginning, or ever the earth was.
