Garden of Eden = Garden of Delight. Since delight also means gracious, hence Garden of Delight = Garden of Graciousness.
The reason Adam was banished from the Garden of Eden was because works and grace cannot co-exist. Since Adam has chosen to rely on works, he cannot depend on grace [Eden=gracious]. If it is by works, then it is not grace.
Galatians 2:21
[Therefore, I do not treat God’s gracious gift as something of minor importance and defeat its very purpose]; I do not set aside and invalidate and frustrate and nullify the grace (unmerited favor) of God. For if justification (righteousness, acquittal from guilt) comes through [observing the ritual of] the Law, then Christ (the Messiah) died groundlessly and to no purpose and in vain. [His death was then wholly superfluous.]
Galatians 5:4
If you seek to be justified and declared righteous and to be given a right standing with God through the Law, you are brought to nothing and so separated (severed) from Christ. You have fallen away from grace (from God’s gracious favor and unmerited blessing).
Law represents works or self-effort or merits.
