Why is the preaching of the cross essential to the gospel?

The preaching of the cross is indispensable to the gospel because it encapsulates the entirety of Christ’s redemptive work and the good news of salvation. According to 1 Corinthians 1:18, the message of the cross, though seen as foolishness by the world, is the power of God for salvation. In proclaiming the cross, Christians reveal the depth of their need for a Savior and the incredible grace God offers through Christ, thus making the cross central to any true understanding of the gospel.
