A very striking image, the thought of majestic cherubim guarding the gates of paradise, shutting out mankind.
What thoughts went through the minds of our ancestors as they looked with fear at the mighty cherubim and with longing at the Garden?
I cannot help thinking of a ragged child being pushed away from a toy shop by a burly store clerk with the words:
These ent for the likes of you, son. These are for the nice kids.
Cherumbim represent the judicial aspect of God. They show His judgement against sin and His exclusion of that which was holy. At Eden they represent judgment on Adam's failing.
In the sanctuary, on the Ark of the Covenant was the mercy seat. This was decorated with statues of two Cherubim. These symbolised God's judicial deals with Israel. No man might approach the mercy seat, except the hight priest once a year on the Day of Atonement, to make intercession for His people.
Yet now there is man who dwells between the Cherubim. In Revelation chapter 4, we see Jesus Christ, the lamb of God being worshipped by Cherubim and hosts of angels. Though man was excluded from earthly paradise by Cherubim, now a man has ascended into heaven and been given access to the heavenly paradise. Through Him, our humanity can be raised to the heights of heaven. Those in Christ have access to heaven through Him.
Just as the high priest would enter into the sanctuary to intercede for Israel, Christ is entered into the heavenly sanctuary. Thriugh Him we have access to the throne of grace. Through Him we are made acceptable to the courts of heaven.
