Why is knowing Jesus Christ important for Christians?

The sermon makes it clear that life without knowledge of Christ is a vain existence. Understanding who Jesus is, and what He has done, is crucial for Christians as it brings genuine significance to life. The Apostle John articulates in 1 John 5:12 that whoever has the Son has life; conversely, those without Him do not have life. This encapsulates the importance of knowing Christ—not merely intellectually but through a relationship rooted in faith and dependency upon Him for salvation and sustenance in life. In Christ, believers find purpose, hope, and completeness.
