Here are a couple of quotes I've enjoyed recently.

“If you read the Scriptures carefully, you will never get the idea that the work of Christ is for well adjusted people who just need a little redemptive boost. It never presents any human condition or dilemma as outside the scope of the gospel. Redemption is nothing less than the rescue of helpless people facing an eternity of torment apart from God’s love.”

— Paul David Tripp Instruments in The Redeemer's Hands (Phillipsburg, NJ: P & R Publishing, 2002), 195

“Jesus is what we drink. “Come to me and drink” (John 7:37).  Jesus doesn’t just have what our souls need; he is what our souls need. Recall John 6:35 “I am the bread of life; whoever comes to me shall not hunger, and whoever believes in me shall never thirst.” He is the bread of life. He is the living water. Our souls were made for Jesus. The ache in our hearts is at root an ache for Jesus. This is how the soul lives on God. It lives on Jesus.”

— John Piper "Out of Your Heart Will Flow Rivers of Living Water" (Minneapolis, Minn.: Desiring God Ministries, February 19, 2011)

“The Christian gospel is not merely that Jesus died and rose again; and not merely that these events appease God’s wrath, forgive sin, and justify sinners; and not merely that this redemption gets us out of hell and into heaven; but that they bring us to the glory of God in the face of Jesus Christ as our supreme, all-satisfying, and everlasting treasure. ‘Christ … suffered once for sins, the righteous for the unrighteous, that he might bring us to God’ (1 Pet. 3:18)”

— John Piper God is the Gospel (Wheaton, Ill.: Crossway Books, 2005), 167
