How do we know Christ is the way to eternal life?

Christ's statement, 'I am the way, the truth, and the life' (John 14:6), is foundational to understanding eternal life. The implication here is that eternal life is not a mere abstract concept but is found in a personal relationship with Christ. By believing in Him and His work on the cross, believers receive the gift of eternal life, as He conquered sin and death on their behalf. Furthermore, Romans 8 discusses the assurance of salvation for those who walk in the Spirit, affirming that eternal life flows from being united with Christ, the source of all life.
