The contemporaries of Jesus did get to know him better after the Ascension  .  We , too are post-Ascension disciples .    
Their witness speaks volumes .  May I add to thinking and deliberating...    prayer  ?   The Spirit that formed Christ in Mary of Nazareth 's womb is yet at work to open us to who he is , today , for each of us  .  And because Jesus is yesterday , today and forever we have in our frail way an open door into who he was to all whom he met 2000 years ago  .  
At least these are my thoughts on the matter ,  Neko  .
