In this verse, there are no options on the route to eternal life – there is only one way, and Jesus is that way.
Here is another way to put this verse; “Faith in Him (Jesus) is Faith in God.”
He (Jesus) is the only path to reach God the Father, representing the absolute truth and the source of eternal life, meaning that salvation and a relationship with God can only be attained through him; essentially, he is the only way to live a meaningful and fulfilling life with God.
