Passage
As he is speaking these things, many believed in him;
As he is speaking these things, many believed in him;
John 8:28 Jesus, therefore, said to them, `When ye may lift up the Son of Man then ye will know that I am <FI>he<Fi> ; and of myself I do nothing, but according as my Father did teach me, these things I speak;
John 8:29 and He who sent me is with me; the Father did not leave me alone, because I, the things pleasing to Him, do always.'
John 8:30 As he is speaking these things, many believed in him;
John 8:31 Jesus, therefore, said unto the Jews who believed in him, `If ye may remain in my word, truly my disciples ye are, and ye shall know the truth,
John 8:32 and the truth shall make you free.'
The verse centers on "speaking", "things", and "believed". It is saying that the verse draws attention to "speaking" and "things", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 29's "and He who sent me is with..." into verse 31's "Jesus therefore said unto the Jews who...", so "speaking" and "things" 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 "speaking" and "things" with trust shaped by these words, not by a vague optimism outside the passage.
