...we should all fortify ourselves against the dark hours of depression by cultivating a deep distrust of the certainties of despair. Despair is relentless in the certainties of its pessimism. But we have seen again and again, from our own experience and others', that absolute statements of hopelessness that we make in the dark are notoriously unreliable. Our dark certainties are not sureties.

We will wait. We will wait till all is made righteous (glorious) according to the word of God.

We would do our theology better if more was at stake in what we said.

What is love for, if not to intensify our affections—both in life and death? But, O, do not be bitter. It is tragically self-destructive to be bitter.

— John Piper

What is sin? It is the glory of God not honored. The holiness of God not reverenced. The greatness of God not admired. The power of God not praised. The truth of God not sought. The wisdom of God not esteemed. The beauty of God not treasured. The goodness of God not savored. The faithfulness of God not trusted. The commandments of God not obeyed. The justice of God not respected. The wrath of God not feared. The grace of God not cherished. The presence of God not prized. The person of God not loved. That is sin.

What then do we learn from Paul's unbroken pattern of beginning and ending his letters this way ("Grace be to you." "Grace is with you.")? We learn that grace is an unmistakable priority in the Christian life. We learn that it is from God the Father and the Lord Jesus Christ, but that it can come through people. Furthermore, we learn that grace is ready to flow to us every time we take up the inspired Scriptures to read them. And we learn that grace will abide with us when we lay the Bible down and go about our daily living. In other words, we learn that grace is not merely a past reality but a future one. Every time I reach for the Bible, God's grace is a reality that will flow to me. Every time I put the Bible down and go about my business, God's grace will go with me. This is what I mean by future grace.

Whenever the strength of God is not recognized as the source of our strength, we are breaking the First Commandment: Do not have any gods before me.

— John Piper

When God appoints the gospel of his Son as the universal remedy for the guilt and corruption of mankind, and we diminish that, the gospel is diminished. And you cannot diminish the gospel without being diminished yourself.

— John Piper

When I believe in Jesus, I am united to Christ. Therefore, what he did and achieved becomes mine by this union through faith alone. His righteous life is imputed to me. What Christ achieved is counted as mine.

— John Piper

When something drops into your life that seems to threaten your future, remember this: the first shockwaves of the bomb are not sin. The real danger is yielding to them. Giving in. Putting up no spiritual fight. And the root of that surrender is unbelief - a failure to fight for faith in future grace. A failure to cherish all that God promises to be for us in Jesus.
