In all my years of attending Mass, I have heard innumerable homilies preached from the pulpit. They range from the instantly forgettable to those that set your heart afire for God. In between, you have memorable ones, but the focus upon God is often diluted by the speaker's desire to be entertaining. Obviously, to impress God, all focus should be on him alone. To achieve this, we need to let God impress us first. It again comes down to letting God do all the work for us.
