24For 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. 25Nor 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. 26Then 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. 27Just as man is destined to die once, and after that to face judgment, 28so 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.
Hebrews chapter 9 is a lot about the Tabernacle, the covenant of God, the Blood of Christ as an atonement for sins. This is really a clear picture of the Gospel message. I think it answers the question: What did the death of Jesus do for mankind?
To me, I can remember this scripture as a assurance of why I believe in Jesus. This is why I am thankful for His death and ultimately His resurrection. It is by this sacrifice that I am made whole, complete, and saved from death.
\\Thank You Lord for saving me, for doing what You did for me on the cross. Thank You for life, heaven, and eternity with You.
