In this statement, Jesus emphasizes the immediacy and certainty of His promise. He speaks of a time that is both future and present, indicating the ongoing and unfolding nature of His work. The 'dead' here can be understood both literally and metaphorically. Spiritually, it refers to those who are separated from God, living in sin, and in need of redemption. Jesus assures that His voice, His teachings, and His call have the power to awaken and transform those who are spiritually dead, offering them new life.
This verse highlights Jesus' divine authority as the Son of God, who has the power to grant life. It is a message of hope, emphasizing that through faith in Christ, believers can experience a spiritual resurrection. The promise of life is not just for the future resurrection at the end of times but is available now for those who hear and respond to His voice. This assurance of spiritual renewal and eternal life is central to Christian faith, encouraging believers to trust in Jesus and His life-giving power.
