How do we know that the Gospel is significant?

The significance of the Gospel is underscored in Paul’s proclamation in 1 Corinthians 2:2 where he states, 'For I determined not to know anything among you, save Jesus Christ, and Him crucified.' This encapsulates the essence of the Christian faith; the Gospel is not merely a religious teaching but the declaration of what God has done for humanity through the death of Jesus. This message fulfills the deepest needs of sinners, offering forgiveness, righteousness, and peace with God. Thus, any preaching that strays from this core message is deemed ineffective and unworthy of proclamation.
