Passage
And the two disciples heard him speak: and they followed Jesus.
And the two disciples heard him speak: and they followed Jesus.
John 1:35 The next day again John stood and two of his disciples.
John 1:36 And beholding Jesus walking, he saith: Behold the Lamb of God.
John 1:37 And the two disciples heard him speak: and they followed Jesus.
John 1:38 And Jesus turning and seeing them following him, saith to them: What seek you? Who said to him: Rabbi (which is to say, being interpreted, Master), where dwellest thou?
John 1:39 He saith to them: Come and see. They came and saw where he abode: and they stayed with him that day. Now it was about the tenth hour.
The verse centers on "disciples", "heard", "speak", "followed", and "jesus". It is saying that the verse draws attention to "disciples" and "heard", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 36's "And beholding Jesus walking he saith Behold..." into verse 38's "And Jesus turning and seeing them following...", so "disciples" and "heard" 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 "disciples" and "heard" with trust shaped by these words, not by a vague optimism outside the passage.
