And that’s why we may approach the throne of Grace with boldness—we do so in Christ—the name which is above every name. The Father’s estimation of His Son’s work on the cross is that it is the ONLY WORK that God acknowledges as righteous (all other works are as filthy rags!)
So, coming to the Father by way of the Son (and the cross) is as a sweet aroma to God, as the perfume of the sacrifice of His Son is a sweet savor! Full atonement is made for sin. I approach His Throne, He sees His Son and is satisfied. The Father now inclines His ear to me, His redeemed child and He gives attention to my [feeble] request and like a loving Father, grants these in accordance with His will.
