Passage
And looking upon Jesus as he walked, he saith, Behold the Lamb of God!
And looking upon Jesus as he walked, he saith, Behold the Lamb of God!
John 1:34 And I saw, and bare record that this is the Son of God.
John 1:35 Again the next day after John stood, and two of his disciples;
John 1:36 And looking upon Jesus as he walked, he saith, Behold the Lamb of God!
John 1:37 And the two disciples heard him speak, and they followed Jesus.
John 1:38 Then Jesus turned, and saw them following, and saith unto them, What seek ye? They said unto him, Rabbi, (which is to say, being interpreted, Master,) where dwellest thou?
The verse centers on "looking", "upon", "jesus", "walked", "saith", "behold", and "lamb". It is saying that the verse draws attention to "looking" and "upon", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 35's "Again the next day after John stood..." into verse 37's "And the two disciples heard him speak...", so "looking" and "upon" belong inside that flow. In John context, the local focus is the identity of Jesus, new birth, eternal life, and belief and unbelief.
A plain takeaway is to answer the verse's own emphasis on "looking" and "upon" with trust shaped by these words, not by a vague optimism outside the passage.
