The purpose of Sabbath is not simply to rejuvenate yourself in order to do more production, nor is it the pursuit of pleasure. The purpose of Sabbath is to enjoy your God, life in general, what you have accomplished in the world through his help, and the freedom you have in the gospel-the freedom from slavery to any material object or human expectation. The Sabbath is a sign of the hope that we have in the world to come.

If a person has grasped the meaning of God's grace in his heart, he will do justice. If he doesn't live justly, then he may say with his lips that he is grateful for God's grace, but in his heart he is far from him. If he doesn't care about the poor, it reveals that at best he doesn't understand the grace he has experienced, and at worst he has not really encountered the saving mercy of God. Grace should make you just.

The Cross is not simply a lovely example of sacrificial love. Throwing your life away needlessly is not admirable — it is wrong. Jesus’ death was only a good example if it was more than an example, if it was something absolutely necessary to rescue us. And it was. Why did Jesus have to die in order to forgive us? There was a debt to be paid — God himself paid it. There was a penalty to be born — God himself bore it. Forgiveness is always a form of costly suffering.

Our culture says that feelings of love are the basis for actions of love. And of course that can be true. But it is truer to say that actions of love can lead consistently to feelings of love.

It fits to glorify God - it not only fits reality, because God is infinitely and supremely praiseworthy, but it fits us as nothing else does. All the beauty we have looked for in art or faces or places - and all the love we have looked for in the arms of other people - is only fully present in God himself. And so in every action by which we treat him as glorious as he is, whether through prayer, singing, trusting, obeying, or hoping, we are at once giving God his due and fulfilling our own design.

God's Kingdom is "present in its beginnings, but still future in its fullness. This guards us from an under-realized eschatology (expecting no change now) and an over-realized eschatology (expecting all change now). In this stage, we embrace the reality that while we're not yet what we will be, we're also no longer what we used to be.

The doctrine of grace and redemption keeps us from seeing any person or situation as hopeless.
