What should be the content of preaching according to Scripture?

Scriptural content in preaching is fundamentally centered on Jesus Christ. 1 Corinthians 2:2 tells us that Paul determined to know nothing but Jesus Christ and Him crucified. This reflects the essence of Christian preaching, which is to proclaim the message of salvation that Christ brought through His life, death, and resurrection. Preaching should not merely inform but transform, addressing the hearts of believers with the deep realities of sin and redemption. It is a call to reflect on one's spiritual condition and to find hope and assurance in Jesus Christ alone, thereby bringing the hearers into a deeper understanding and relationship with their Savior.
