Why is the ascension of Christ important for salvation?

The ascension acts as a divine confirmation of Christ’s victory over sin and death, which is central to the gospel message. Through His ascension, Jesus not only secured a place at the right hand of the Father but also guarantees that those who believe in Him will receive eternal life. As articulated in John 17:2, Christ’s authority over all flesh empowers Him to grant eternal life to His chosen people. Moreover, the ascension assures believers that Christ as the God-man fulfills the covenant of grace, acting as both their Savior and intercessor. This event validates the power of His sacrifice, leading to the promise of salvation for all who trust in Him, fulfilling His statement, 'It is finished.'
