Community service has become a patch for morality. You can devote your life to community service and be a total schmuck.

Conversation with God leads to an encounter with God. Prayer turns theology into experience.

Even if 80 percent of the population of a country are Christian believers, they will have almost no cultural influence if the Christians do not live in cultural centers and work in culture-forging fields such as academia, publishing, media, entertainment, and the arts. The assumption that society will improve simply be more Christian believers being present is no longer valid.

Every artifact of human culture is a positive response to God's general revelation and simultaneously a rebellious assertion against His sovereign rule over us.

Every one of our sinful actions has a suicidal power on the faculties that put that action forth. When you sin with the mind, that sin shrivels the rationality. When you sin with the heart or the emotions, that sin shrivels the emotions. When you sin with the will, that sin destroys and dissolves your willpower and your self-control. Sin is the suicidal action of the self against itself. Sin destroys freedom because sin is an enslaving power.

Everyone will be forgotten, nothing we do will make any difference, and all good endeavors, even the best, will come to naught. Unless there is God. If the God of the Bible exists, and there is a True Reality beneath and behind this one, and this life is not the only life, then every good endeavor, even the simplest ones, pursued in response to God's calling, can matter forever.

Faith gives you a concept of the dignity and worth of all work, even simple work, without which work could bore you.

Falling in love in a Christian way is to say,'I am excited about your future and I want to be part of getting you there. I'm signing up for the journey with you. Would you sign up for the journey to my true self with me? It's going to be hard, but I want to get there.

For indeed, grace is the key to it all. It is not our lavish good deeds that procure salvation, but God's lavish love and mercy. That is why the poor are as acceptable before God as the rich. It is the generosity of God, the freezes of his salvation, that lays the foundation for the society of justice for all. Even in the seemingly boring rules and regulations of tabernacle rituals, we see that God cares about the poor, that his laws make provision for the disadvantaged. God's concern for justice permeated every part of Israel's life. It should also permeate our lives.

Friends become wiser together through a healthy clash of viewpoints.
