Why is knowing Christ central to Christian faith?

The Christian faith rests on the reality that no one can come to know God apart from Christ. In John 1:29, John the Baptist identifies Jesus as the Lamb of God who takes away the sin of the world, highlighting the necessity of His sacrificial death for our salvation. This affirmation is foundational because it points to the sufficiency of Christ's work and reveals that our faith is not based on human merit, but solely on the grace extended through Christ. Thus, knowing Christ personally is essential for spiritual life and the assurance of salvation.
