At-one-(ment) with God

I have been reading through the book of Leviticus. Although there are many details I do not understand there are some ideas which are continually repeated: God is holy, we are not, and it is necessary to make atonement with blood for our sin. The primary role of the Levite priest is to "make atonement", a praise that is repeated countless times. Christians can be thankful that God has graciously provided both a perfect priest and a sacrificial lamb (a scape goat!), Jesus to make atonement, once and for all.

The painting is the Adoration of the Mystic Lamb which is part of the Ghent Altarpiece painted by Hubrecht and Jan van Eyck.
