A significant teaching within the 'Futurist' interpretation of scripture is the belief that we are living in the 'last days'. This expression appears literally six times in the New Testament although there are other similar expressions used throughout the Bible. Prophecies which are contextually connected to where these expressions are found are deemed to be about to be fulfilled. The six uses of this expression are listed below together with a brief comment as to why the 'last days' belong to the past and not to the present nor the future:
'[Jesus]...Hath in these last days spoken to us by his son...1'
This part of the Bible was written before AD70. The implication is that the 'last days' were before AD70.
'...Ye have heaped up treasure for the last days'.
(James 5: 3)
The letter of James was written circa AD48-60. The 'last days' were about then.
Peter explains the remarkable events of Pentecost by quoting from Joel, 'And it shall come about in the last days, saith God, I will pour out my spirit on all flesh...'
Pentecost took place in AD34 during the 'last days'.
The implication from the above three references is that the 'last days' were either then present, or were coming soon. A pattern is emerging.
'Now the Spirit speaketh expressly, that in the latter times [last days] some shall depart from the faith, giving heed to seducing spirits, and doctrines of devils'. (...) 'Forbidding to marry, and commanding to abstain from meats...'_
(1 Timothy 4:1,3 written circa AD64)
'This know also that in the last days perilous times shall come'...
(2 Timothy 3:1, written circa AD66/67)
Paul's first and second letters to Timothy are private pieces of correspondence concerning church government and various pastoral issues. If the expression 'latter days' (last days) refers to a specific period many centuries into the future, then the associated teaching would fall totally outside the context of these letters. Why would Paul warn Timothy of matters that would not become relevant to Timothy personally? Would it not make more sense if the 'last days' were to arrive in the near future i.e. a few years - or even decades at most - after the mid AD 60s?
In Paul's first letter to Timothy (4:3) he warns against people who forbid marriage and enforce vegetarianism. One community of Essenes lived near En Gedi (on the shores of the Dead Sea) from the second century BC until circa AD70. This community practised both celibacy and vegetarianism. The warning is that these practices may become widespread and ought to be opposed by Timothy now.
If we accept that Paul's teaching was directed to (then) contemporary issues, then we must accept that his use of the expression 'latter days' (which is identical in meaning to last days) referred to times in the late AD60s.
Did perilous times come soon after the time of writing? Did many 'fall away from the faith'? The Fall of Jerusalem (AD70) was certainly one such time of peril and certainly many unbelieving Jews would have fallen away from the practice of their faith.
'...there shall come in the last days scoffers and saying 'where is the promise of his coming'?_
(In 2 Peter 3:3 written circa AD65-68.)
