John Chrysostom
"Let us draw near," he says, "with a true heart." Who are those who draw near? Those who are holy by faith and by spiritual service.
"With a true heart, in full assurance of faith," because here there is nothing visible. The priest, the sacrifice, and the altar are invisible. There too the priest was not visible. He stood within, while all the rest, the whole people, were outside.
But here the Apostle expresses not only that our Priest entered the holy place. He had indicated this with the words, "a great Priest over the house of God." He also says that we enter. Therefore he says, "in full assurance of faith."

One may believe with doubt. Even now there are many who say that there will be a resurrection for some, but not for others. This is not fullness of faith. We must believe as firmly as we trust visible things, and even much more.
In visible things one may be mistaken, but not there. Here we perceive by sense, but there by the spirit.
"Having our hearts sprinkled from an evil conscience." Here he proves that not only faith is required, but also a virtuous life, and that we be conscious of nothing evil in ourselves. Those who do not live entirely so are not admitted into the holy place. For it is holy, and the Holy of Holies. Therefore no unclean person enters there.
They washed the body, but we wash the conscience. Even now one must be washed, but now in virtue.
"And having our bodies washed with pure water." Here he speaks of the font of baptism, which cleanses not the body, but the soul.
What does "let us draw near with a true heart" mean? It means without hypocrisy: "Woe to fearful hearts and slack hands" (Sir 2:12). Let there be no falsehood in you, he says. Let us not say one thing and think another, for this is falsehood.
Let us not be fainthearted, for this is foreign to a true heart. Faintheartedness comes from unbelief. How shall we attain this? If we have full faith within us.
"Having our hearts sprinkled from an evil conscience." Why did he not say "cleansed," but "sprinkled"? To show the difference between sprinklings. One is from God, the other from us. To sprinkle and wash the conscience is from God. To draw near sincerely and with full faith is from us.
Then the Apostle strengthens faith by pointing to the truthfulness of Him Who promised. What does "and having our bodies washed with pure water" mean? He speaks either of water that makes pure, or of water that has no blood in it.
