Every sermon is a "salvation sermon"

Preaching is a means of grace to assist the saints to persevere. Perseverance is necessary for final salvation. Therefore, every sermon is a "salvation sermon"—not just because of its aim to convert sinners, but also in its aim to preserve the holy affections of the saints and so enable them to confirm their calling and election and be saved.

When you look down on the bible...

"[And] surely, once we hold God's Word in contempt, we shake off all reverence for him."
  -- Calvin, Institutes, Book II, i, section 4

The Most Pleasant Life

When he was on his deathbed, Matthew Henry said to a friend, "You have been asked to take notice of the sayings of dying men - this is mine: that a life spent in the service of God and communion with Him is the most pleasant life that anyone can live in this world."
