Why is Christ's ability to give eternal life important for Christians?

Christ's unique authority to grant eternal life sets Him apart from all others. In John 17:2, it states that Jesus has the ability to give eternal life to whom He wishes. This doctrine is fundamental to the Christian faith as it underscores the reality that salvation is entirely at His discretion and not contingent on human effort. Eternal life signifies not just a continuation of existence but an intimate relationship with God, where believers are assured they will one day dwell in His presence. This assurance provides profound comfort and hope to Christians, knowing that their eternal destiny is secured by Christ's finished work.
