When the Lord came into the world He could say, "A body hast Thou prepared Me." In the volume of the book of His eternal counsels the subject is Christ as a Man on earth, in a body, doing God's will. In the Old Testament account of the counsels it is ears for listening and willingness-in the New Testament it is a body, for the counsels are carried out by Him becoming man. He came from heaven, was born of the Holy Spirit.
No sacrifice made by man of Adam's race would do. It must be the sacrifice of a Man from heaven, a perfect Man, to redeem Adam's race; this Christ came to do. He came to do God's will, "By the which will we are sanctified, through the offering of the body of Jesus Christ once for all."
This Man (Christ) offered one sacrifice for sins and forever sat down on the right hand of God. It is by this one sacrifice of Christ that the believer is perfected now and forever.
We belong to the house of God. Shall we not draw near with hearts true, in full assurance of faith, with a good conscience and our bodies washed with pure water (all that's outward in our lives, clean). The memory of the cross and the blood of Christ, together with the body washed with water of the Word, prepare our hearts for worship as we enter the holiest.
We should consider one another to encourage and love one another.
The apostate can only expect the wrath of God. The day of apostasy is the day mentioned as approaching, warning those who trifle with the gospel instead of laying hold of it by faith.
The apostle would encourage the faithful by calling to mind the former days when there was much energy and persecution for the gospel spoken publicly. They were not to lose their confidence. They had need of much patience in view of the promise, the coming of the Lord.
