In my morning studies on Daniel 10 I was delighted to find this paragraph from Sinclair Ferguson on what it is like to truly encounter the glory and grace of God as Daniel did. He writes:
Such people who have seen God's glory and grace can never be the same again. They have come to know who God is, and in His presence they come to know what they are themselves in their need and by His grace. They lose their taste for all that is trivial. They learn to live as Daniel did, near to God. They are never far from heaven because they know they are no longer distanced from it by the guilt of sin. Forgiven and cleansed, they have a presence about them. It is the presence of God (Sinclair Ferguson, Mastering the Old Testament: Daniel, p. 212).
