In case you’re confused:
The gospel is not a summons to kingdom living or a message about what we can do for God or a description of our efforts at cultural transformation. The gospel, according to Paul’s summary in 1 Corinthians 15, is the good news that Jesus Christ died for our sins and rose again on the third day.
—Kevin DeYoung, The Good News We Almost Forgot: Rediscovering the Gospel in a 16th Century Catechism (Moody Publishers, 2010), 41.
The gospel has many implications for how we are to live in this world, but don’t be misled by pop theology: those things are not the gospel. The gospel is about a holy God, a sinful race, and what Christ has done to reconcile God to man.
There is nothing more important in Christian theology that our theology of the cross. We must speak clearly that the heart of the gospel is the good news of divine self-satisfaction through divine self-substitution. Never compromise on the cross. Never dilute the message of the cross. And never stop glorying in the cross where Christ accepted the penalties that should belong to us so that we can claim the blessings that would otherwise belong only to Him.
