Exodus 24:9-18 click here for the reading
Moses is on the mountaintop for 40 days and nights? This is more than going hiking with God. The exploration of relationship and self within the presence and mystery of God is apparent (or is supposed to be). That is why it is called a mountaintop experience!
My pastor calls this type of encounter with God, explosion. We don't really do anything to invite God in, or be intentional about spending time with God....God just shows up.
We have all had mountain top experiences of God's presence....an ah-ha moment, an epiphany, a revealing. God showing up in the mountaintop reveals something about who we are and about who God is. What mountaintop experience have you had?
