How do we know that eternal life is found in Jesus Christ?

John 17:3 defines eternal life as knowing the only true God and Jesus Christ whom He sent. This knowledge transcends mere intellectual understanding and encompasses a personal, saving relationship with Christ. In the study of Revelation, we are reminded of the faithful nature of Christ, who completed the work of salvation. His ability to grant eternal life as King reflects His divine authority and sufficiency as our Savior. The assurance we hold as believers is rooted in the promise of God and the finished work of Christ on the cross.
