The following are my favorite quotes from the book Living the Cross Centered Life: Keeping the Gospel the Main Thing by C.J. Mahaney.
“‘We never move on from the cross, only into a more profound understanding of the cross.’ The cross and its meaning aren’t something we ever master.” – page 17.
“‘My God, only You could show me what a wretched sinner I am and make it the greatest news I’ve ever heard!'” – page 20.
I just recently read and completed this book. Its main thesis is that the Gospel is not something believers should “move on” from after conversion. Instead, Christians should seek to grow in deeper love with the Gospel everyday and allow its reality to affect every aspect of who they are and the way they live. This excerpt from the book seems to summarize its main theme rather well:
I can hear you asking, ‘But don’t I need more than the cross?’
In one sense, the answer is no. Nothing else is of equal importance. The message of Christ and Him crucified is the Christian hope, confidence, and assurance. Heaven will be spent marveling at the work of Christ, the God-Man who suffered in the place of us sinners.
