The book of Ezekiel is all about the Glory of God. You can see it stamped through the entire book. And when we find ourselves in difficult situations or ministries, how do we persevere? By seeing God's greatness and glory and delighting in who he is.
"Such was the appearance of the likeness of the glory of the Lord. And when I saw it, I fell on my face, and I heard the voice of one speaking." Ezekiel 1:28b
