Charles Ellicott Commentary Hebrews 10:22

"let us draw near with a true heart in fulness of faith, having our hearts sprinkled from an evil conscience: and having our body washed with pure water," — Hebrews 10:22 (ASV)

Let us draw near.—See Hebrews 10:1; also Hebrews 4:16; Hebrews 7:25; Hebrews 11:6.

With a true heart.—“True,” the word used in Hebrews 8:2; Hebrews 9:24, a real—i.e., a sincere heart. As in Hebrews 6:11 we read of full assurance, or rather, fulness of hope, so here of fulness of faith. Without this there could be for us no living way (Hebrews 10:20) for entering into the holiest place. The thought of the whole verse connects itself with the priestly character of those who are the people of God (Exodus 19:6; Revelation 1:5–6).

It is as priests that they enter the house of God, sprinkled with the blood of atonement (Hebrews 12:24; Hebrews 9:14; Leviticus 8:30; 1 Peter 1:2), and with all defilement washed away (Leviticus 8:6). Sprinkled from an evil conscience: that is, freed by means of the “sprinkling” from a conscience defiled by guilt. In the last words there is a clear allusion to baptism, as the symbol of the new life of purity (Ephesians 5:26; Titus 3:5; 1 Peter 3:21).
