Passage
And if I also iudge, my iudgement is true: for I am not alone, but I, and the Father, that sent mee.
And if I also iudge, my iudgement is true: for I am not alone, but I, and the Father, that sent mee.
John 8:14 Iesus answered, and sayde vnto them, Though I beare recorde of my selfe, yet my recorde is true: for I know whence I came, and whither I go: but ye cannot tell whence I come, and whither I goe.
John 8:15 Ye iudge after the flesh: I iudge no man.
John 8:16 And if I also iudge, my iudgement is true: for I am not alone, but I, and the Father, that sent mee.
John 8:17 And it is also written in your Lawe, that the testimonie of two men is true.
John 8:18 I am one that beare witnes of my selfe, and the Father that sent me, beareth witnes of me.
The verse centers on "iudge", "iudgement", "true", "alone", "father", and "sent". It is saying that the verse draws attention to "iudge" and "iudgement", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 15's "Ye iudge after the flesh I iudge..." into verse 17's "And it is also written in your...", so "iudge" and "iudgement" 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 "iudge" and "iudgement" with trust shaped by these words, not by a vague optimism outside the passage.
