What does the Bible say about neglecting the gospel?

The Bible cautions believers against neglecting the gospel, as seen in Hebrews 2:1-4, which states that we ought to 'give the more earnest heed to the things which we have heard.' Neglecting the gospel is a serious matter because it can lead to spiritual drifting and ultimately to judgment. The author of Hebrews emphasizes the importance of being diligent in listening to the gospel, as it is the very message that brings salvation. If believers allow the glorious truths of the gospel to slip, they risk missing out on the precious relationship with Christ and the assurance of salvation.
