Look to the Bible and not your feelings as the basis of the Christian life.

To focus our mind on the task at hand-with fierce concentration-m akes for a productive use of time.

The idea of being the Substitute in offering an atonement to satisfy the demands of God’s law for others was something Christ understood as His mission from the moment He entered this world and took upon Himself a human nature. He came from heaven as the gift of the Father for the express purpose of working out redemption as our Substitute, doing for us what we could not possibly do for ourselves.

It's a sin to bore people.

It’s dangerous to assume that because a person is drawn to holiness in his study that he is thereby a holy man. There is irony here. I am sure that the reason I have a deep hunger to learn of the holiness of God is precisely because I am not holy. I am a profane man—a man who spends more time out of the temple than in it. But I have had just enough of a taste of the majesty of God to want more. I know what it means to be a forgiven man and what it means to be sent on a mission. My soul cries for more. My soul needs more.

Cynicism and skepticism are the crudest form of quasi-intellectualism... Let the cynic become cynical of his cynicism and the skeptic skeptical of his skepticism and join the battle.

It is important for us to make a distinction between the spiritual fruit of joy and the cultural concept of happiness. A Christian can have joy in his heart while there is still spiritual depression in his head. The joy that we have sustains us through these dark nights and is not quenched by spiritual depression. The joy of the Christian is one that survives all downturns in life.
