Jhn 5:38
And ye have not his word abiding in you:
for/because (hoti) whom he hath sent, him ye believe not.
Jhn 5:39
Search the scriptures; for in them ye think ye have eternal life: and they are they which testify of me.
Jhn 5:40
And ye will not come to me,
so that/with the intention that (
hina) ye might have life.
Jhn 5:44
How can ye believe, which receive honour one of another, and seek not the honour that cometh from God only?
I read
hoti there as because,
either causal, giving the reason why they have not God's word abiding in them v. 38 (they have not done what Jesus refers to later as believing Moses words 5:47; "having heard and LEARNED from God" 6:45, which if they had done, they would be coming to Him for the right reasons, to hear and learn from Jesus, whom Moses said they had to hear and learn from (Deut. 18:15);
or diagnostic, giving the reason why Jesus
can tell that they have not God's word abiding in them. It's obvious to Me that you do not have God's word abiding in you, because you don't believe in the one whom, through Moses and the other prophets, He promised to send.
I don't think 5:40 is saying they will not come to Jesus (full stop). It says they will not come to Jesus for the right reason,
so that they might have life by receiving Him and His message. They
are coming to him, but for wrong reasons.
