We were sinful but can now dwell in a sinless Garden, because Jesus died for us. The only thing that barred us out was our sins. And death pays for sins. So Jesus took that rule and died for us, so we could enter. Put the two pictures together, and realize that the Lamb, Jesus, took the death we would have received had we tried to enter.
Death only needs to be paid once for every sinner.
And then in the dream I remember preaching of the holiest of holies. He had to walk past the veil with cherubims on it, with the same creatures that stood by the sword in the Garden, because death would occur by the cherubims should anyone enter. And death had to know there was already a death. He is showing you that death already was paid for Him. My blood would have been shed at the entrance had I tried to enter the Garden.
