I appreciate your emphasis on how Adam walked with God and recognised his presence. As you outlined, before the fall, man enjoyed unhindered fellowship with God and after sin was introduced, man hid himself from the presence of God. There was no shame or guilt or fear before Adam’s disobedience and many years after redemption we still find that these things are a huge distraction and hindrance even amongst believers. Many people struggle with a consistent fellowship with God. Some do not recognise his voice or understand his will. All these uncertainties are as a result of man’s separation from God.
If only we will believe totally and plunge ourselves completely into the word of God, we will find that the effects of sin on our soul/physical senses begin to dissipate. Hence the importance of renewing our mind with God’s word and being led by the Holy Spirit.
Just as a fish will find it difficult to survive outside water, man struggles and walks around in confusion when he is outside his natural habitat; the presence of God. James 4:8 encourages us to draw near to God, cleanse our hands and purify our hearts. As we embrace the gift of redemption we are transformed and changed. The old Adamic nature is displaced and as Christ is, so are we in this world.
