Your experience as a Christ follower is spiritual. The author is now contrasting the 2 mountains, that of Sinai and Zion. The first was physical and the second spiritual. The first was where the law was given in order to move the people into holiness. It failed. The second was a complete transformation of the heart. It has succeeded.
We all need to be reminded of the relationship with God that we have been called into.
“You have not come to a mountain that can be touched and that is burning with fire; to darkness, gloom and storm; 19 to a trumpet blast or to such a voice speaking words that those who heard it begged that no further word be spoken to them, 20 because they could not bear what was commanded: “If even an animal touches the mountain, it must be stoned to death.” 21 The sight was so terrifying that Moses said, “I am trembling with fear.”(Hebrews 12 v 18-21)
This relationship is not untouchable. God’s presence had come upon Mount Zion and Moses was called up that mountain as the representative of the people. But they themselves were commanded not to touch it. The presence of God was too holy for them to set their feet on it or touch it. “Put limits for the people around the mountain and tell them, ‘Be careful that you do not approach the mountain or touch the foot of it. Whoever touches the mountain is to be put to death.” Exodus 19:12. Their sin separated them from their Holy God.
This relationship is not unlistenable. In what sounds like an explosive volcano taking place the people wanted it to stop. ““Speak to us yourself and we will listen. But do not have God speak to us or we will die.” Exodus 20:19. Their sin meant they wanted a mediator they couldn’t bear the holy Word of God.
This relationship is not unapproachable. On the giving of the 10 commandments, “When the people saw the thunder and lightning and heard the trumpet and saw the mountain in smoke, they trembled with fear. They stayed at a distance… Moses said to the people, “Do not be afraid. God has come to test you, so that the fear of God will be with you to keep you from sinning.” The people remained at a distance, while Moses approached the thick darkness where God was.” Exodus 20:18-21. Their sin caused them to back off from God.
So of course the reverse is true. We will see that tomorrow.
But today be thankful for Jesus. For through Him you are not separated; you can hear God speak to you and you do draw near with full assurance.
This is the truth of your relationship with God.
