From the study
David-
"O God, you are my God,
earnestly I seek you;
my soul thirsts for you,
my body longs for you,
in a dry and weary land
where there is no water. I have seen you in the sanctuary
and beheld your power and your glory.
Because your love is better than life,
my lips will glorify you.
I will praise you as long as I live,
and in your name I will lift up my hands." (Psalm 63:1-4)
What effect does the Spirit seem to have upon their relationship with God?
When someone has a divine encounter- it changes everything. The Holy Spirit opened David's eyes to the unseen spirit realm. It is one thing to know about the invisible spirit realm, it is another to experience it.
Just like Peter, James, and John, they were forever changed by their Mount of Transfiguration experience.
