This sign proposes a different reading:
John 3 contains the conversation that Jesus has with Nicodemus. Contextually, the conversation is about why Jesus is present in that age and how Nicodemus should respond. The conversation is not about Jesus returning.
On identifying the pastor's contact details the following fruitful email exchange ensued (editted):
Dear Pastor XXXX,
I had the pleasure of being in the XXX area today. In passing the XXXXX church I observed the signboard. The signboard had a message that was purported to be from John 3:14.
I immediately found the verse to be at odds with my Bible (NIV). Jesus is in discussion with Nicodemus. In the discussion there is a focus on why Jesus is present at that time, and on the respose that Nicodemus should have. Contextually, the verses do not relate to the second coming as the signboard would suggest.
For my education could you please advise whether XXXXXs use a version of John that differs from versions customarily used in Protestant churches in Sydney?
Let me apologise regarding the message on the board. The message is an error and should read John 14:3. I have attempted to have it corrected immediately.
It is our belief that John 14:3 is speaking of the second coming of Jesus.
XXXXXXX use the same versions of the Bible that are found within mainstream protestant churches today. I enjoy the NKJV as my personal favourite.
