ISB ~ Hebrews 4 v16

confidence:Or, “boldness” (CCC 2778).

the throne of grace:The heavenly throne of the Father (8:1; 12:2), in whose presence Christ intercedes for us as high priest (7:25).

• In ancient Israel, the Lord sat enthroned on the wings of the cherubim over the Ark of the Covenant (2 Sam 6:2; Is 37:16). Given the Tabernacle imagery that permeates the theology of Hebrews, the throne of the Father is probably envisioned as the Ark of the heavenly sanctuary (Rev 11:19). It is here that God gives us mercy after we sin and grace to keep us from sin (CCC 2795).
