I will bet my left leg and say that the carpenter from Nazareth does not appear in the next month, year, decade, century or ever.
My left leg wont look too good in a century...So I suggest you take the bet now and fix a contract fulfillment time for 2050.
Only the Father knows the appointed time of Christ's return. Since, I am not God the Father it would be vanity for me to take such a bet. If Christ doesn't come until I am long in the grave I could care less because I know that I serve a risen Savoir that will come to call his own back home.
