God: "I looked for someone to take a stand for me, and stand in the gap" (Ezekiel 22:30)
Since expository preaching begins with the text of Scripture, it starts with God and is in itself an act of worship, for it is a declaration of the mighty acts of God. It establishes the focus of the people upon God and His glory before any consideration of man and his need.
Grace is favor shown to people who do not deserve any favor at all... We deserve nothing but hell. If you think you deserve heaven, take it from me, you are not a Christian.
