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 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?
John 1:39 He saith unto them, Come and see. They came and saw where he dwelt, and abode with him that day: for 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 looking upon Jesus as he walked..." into verse 38's "Then Jesus turned and saw 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.
