"Having therefore, brethren, boldness to enter into the holiest by the blood of Jesus." Hebrews 10:19
Nothing will satisfy a living soul but coming "into the holiest." He wants to have communion with God, the holy, holy, holy Lord God of hosts. He is not dealing with a God distant and afar off--an idol, a God in whom he has neither faith, nor hope, nor love; who can neither see, nor hear, nor save; a God of his own conception or of some indistinct, traditional opinion; but he feels in his very conscience that he is carrying on a sacred and holy communion with the God of heaven and earth, the God who has made himself in some measure known to his soul as the God and Father of the Lord Jesus Christ. With him he has to do; to him he must come; and with him he must hold holy communion. Before his heart-searching eyes he feels he stands; into his ever-open ears he pours his petition; to his mercy and pity he appeals; his compassion he craves; his love he seeks; his salvation he longs for; and his presence above all things he earnestly desires. So he must come into the holiest, for there God dwells; and to come unto God is to come there.
The man who thus feels and acts is an Israelite indeed in whom there is no deceit; one of the true circumcision who worship God in the Spirit, rejoice in Christ Jesus, and have no confidence in the flesh. Others are satisfied with the courts of the house, with admiring the external building, or the painted windows, carved pews, and long drawn aisles; with the mere worship of God as so much lip service. But the living soul goes beyond all that into the very heart of the sanctuary itself. As the high priest on the day of atonement did not tarry among the people in the court, nor with the priests in the holy place, but pressed on, ever pressed on through the thick veil until he got into the holy of holies; so with the saint of God--he does not tarry in the outer court with the profane, nor in the sanctuary with the professor, so as to be satisfied with seeing God with a veil between. But he must come into that immediate presence of God, where he may see something of his grace, behold something of his glory, feel something of his mercy, and taste something of his power. And this makes him press forward into the holiest.
