In Genesis Adam and Eve are living in the garden enjoying the presence of God but they did not eat from the tree of life. There is a difference between being in His presence and receiving his Life. Life is our need. The life flowing from God is what the devil will try to keep us from. If he can keep us from receiving Life eventually he will deceive us to believe a lie and that eventually results in us being cast out of His presence.
If we are reconciled to God by his death, how much more should we be saved by His life? Romans 5.9.
We can live in the shadow of His death and still not feast at the table of life! The life is in Him. It is only Life that swallows up the death that works in us; His life is where the power and life is!
The devil will seek to keep you from drawing from his Life! Satan loves to bring to your attention and Gods, all of your past failures and sins; accusing us that we are not worthy to be in God's presence or that God will not listen to us. “You have sinned too much, God is sick of you. It’s just too much for Him to forgive now. He not going to help you and He is very angry with you. He is too holy to help you or even listen to you.” Accusations!

Friend, in the last days of the glorious church, Satan will no longer be able to accuse the church for two reasons: One, the church trusts in the righteous garments provided by Father, fully overcoming the devil's accusations and secondly they will have learned to draw from the Holy Spirits power, to live powerful, disciplined, Spirit-led lives with nothing left to accuse.
