How do we know Jesus is the source of eternal life?

Jesus explicitly states in John 5:39-40 that the scriptures testify of Him, highlighting that real eternal life is found in coming to Him, not merely in the act of searching the scriptures. Colossians 1:16-17 further asserts that by Him all things were created and in Him all things consist, underscoring His role as the source of life. This connection between Jesus and eternal life is paramount to understanding salvation; it emphasizes the necessity of recognizing His preeminence in all things, including our relationship with God.
