Atonement

Leviticus 16:10 ESV
but the goat on which the lot fell for Azazel shall be presented alive before the Lord to make atonement over it, that it may be sent away into the wilderness to Azazel.

Our sins were lifted and carried by Jesus far from the presence of God so that we could come close. He gave His blood that sins might be removed and remembered no more, as far apart as East is to West.
He came to live among us and to completely represent us before the Lord, to make and be that atonement that was required.

Leviticus 16:30-31 NIV
because on this day atonement will be made for you, to cleanse you. Then, before the Lord, you will be clean from all your sins. 31 It is a day of sabbath rest, and you must deny yourselves; it is a lasting ordinance.

Jesus allows us to enter the rest of God, even in a world still groaning under the curse of sin. A table has been set in the presence of our enemies.

The day is coming when what has begun will be complete and the children of God will be revealed. Our journey will be at end and creation restored.
