i see man in the beginning in full communion with God. after sin the glory and knowledge of that experience was still fresh in Adam's mind. he was keenly aware of what he had lost. i imagine his hungering and thirsting for God was very great. I imagine Adam grasping every blessing earnestly and taking hold of every communion with God by faith tho quench his longing for the presence of God he could now only enjoy by faith. Eden still glowed at the entrance, the angel was still standing there wielding heavenly fire people could go and witness it. The creation was still not so far from God. the oral tradition was strong.
over the millennia the darkness over man has been deepening from the light shining so strong in those days. And the revelation of God has been growing brighter to meet the increasing darkness and deeper and deeper misapprehension of God. It seems as this permitted development of evil is deepening it is being met by a increasingly powerful display of the Character of God. God's plan and the timing of each revelation of God by the Power of the Holy Spirit is perfect, and meeting the needs of fallen man struggling in the grasp of sin.
The Holy Spirit has been laboring in every heart from the moment Adam fell. The Old testament is filled with references to the Holy Spirit. In Psalms 51 David prays, Take not thy Holy Spirit from me, cast me not away from your presence. The ongoing tension between a purely unselfish and powerful and gracious God, and the small selfish and ugly mean spirited humanity has no rest. God is not willing for anyone to perish, he is working to save every soul possible in spite of themselves. When the Spirit comes He will reveal sin, and reveal Christ because Christ has returned to heaven, and reveal the judgement of God again sin because the leader of the rebellion against God has been fully exposed, and judged and cast out.
It was by faith Jesus walked as a human being, constantly maintained and empowered by the work of the Holy Spirit that made His Father known to Him, and was the source of every victory and revelation of God's mercy in acts of Love towards man, and profound worship of God. God wants us to know the love expressed and held towards Jesus is the same Love he holds us in. By the same Spirit that empowered Jesus he Speaks the creation power of God in us to recreate us, and transform us, and inspire us.
We are human and fallen, we struggle to comprehend God. He had made himself known and will increasingly make himself known that we may be filled and preserved and empowered by this Holy Spirit again as Adam was and even more so. From the last of John 17. We do not know what we shall be, but we know when he appears we shall be like him.
