Finishing up Hebrews 9

Heb 9:16-22

"In the case of a will, it is necessary to prove the death of the one who made it, because a will is in force only when somebody has died; it never takes effect while the one who made it is living. This is why even the first covenant was not put into effect without blood. When Moses had proclaimed every commandment of the law to all the people, he took the blood of calves, together with water, scarlet wool and branches of hyssop, and sprinkled the scroll and all the people. He said, 'This is the blood of the new covenant, which God has commanded you to keep.' In the same way, he sprinkled with the blood both the tabernacle and everything used in its ceremonies. In face, the law requires that nearly everything be cleansed with blood, and without the shedding of blood their is no forgiveness."

For a will to come into play, the maker of the will has to die. Until then, the will is useless.
So, for God's will to happen, Jesus had to die. And now it is in force.
Even God's old covenant had blood to put it into effect (though of animals of sacrifice). Blood is necessary for these things.

v 23-28

"It was necessary, then, for the copies of the heavenly things to be purified with these sacrifices, but the heavenly things themselves with better sacrifices than these. For Christ did not enter a man-made sanctuary that was only a copy of the true one; he entered heaven itself, now to appear for us in God's presence. Nor did he enter heaven to offer himself again and again, the way the high priest enters the Most Holy Place every year with blood that is not his own. Then Christ would have had to suffer many times since the creation of the world. But now he has appeared once for all at the end of the ages to do away with sin by the sacrifice of himself. Just as man is destined to die once, and after that to face judgment, so Christ was sacrificed once to take away the sins of many people; and he will appear a second time, not to bear sin, but to bring salvation to those who are waiting for him."

I think the things from the first covenant are the 'copies' that vs 23 refers to. They needed to be purified with the blood of sacrifices. And how much more do the heavenly things need - if the others are just copies? There needs to be something significantly greater for the 'original'.
Christ entered heaven itself! That's a big deal. To appear for us in God's presence. He's our mediator to God. He has cleansed our sin and stands in that gap for us so we can get God's promises!
Jesus didn't go again and again like the old-covenant high priests. Every year making sacrifices for themselves and the people... no, then he would suffer over and over again. But his sacrifice was worth more than one year. It was to cover our multitude of sins for those people that would accept it. As we are to die once and face judgment, so Jesus died once to take our sins. His sacrifice meant that much. He was God. Not just another person.
And he will come again... to bring salvation to those who are waiting for him.
Are we waiting? Attentively? Eagerly looking forward to that day?
