When Jesus comes back, it will be a very joyous and great time for us. And this end time Second Coming of Jesus is an interesting subject theologically and eschatologically.
Yet, I believe urgency and desire should come from ‘heart knowledge’ rather than ‘head knowledge’.
We can know many things about this Second Coming of Jesus, but unless you have this ‘heart knowledge’, unless you have this urgency to love Him and want to meet Him, ‘head knowledge’ could be of no use.
