Why is the preaching of Christ important for salvation?

The preaching of Christ is vital because, according to Romans 10:17, 'So then faith comes by hearing, and hearing by the word of God.' This reminds us that without the proclamation of the gospel, individuals cannot know Christ or what He has done for them. The message preached is about Christ and His work—His life, death, and resurrection—which is the basis for salvation. As Philip preached to the Ethiopian eunuch in Acts 8, he explained the Scriptures concerning Jesus, showing that the entire storyline of the Old Testament culminates in Him. Therefore, the act of preaching not only informs but also draws the heart to believe in the only Savior.
