First of all, for a pre-tribulationist to believe that interpretation of this verse, he has to assume a “once saved always saved” position, which is in itself un-biblical. In actuality, this verse applies to all men, whether they are un-saved or Christians, who still have the free-will to fall.
Notice that the New Testament which is addressed to Christians warns the readers that to disobey God invites his wrath upon them.
Look up the following verses in context:
Ro 1:18 -
For the wrath of God is revealed from heaven against all ungodliness and wickedness of men who by their wickedness suppress the truth.
Ro 2:5 -
But by your hard and impenitent heart you are storing up wrath for yourself on the day of wrath when God’s righteous judgment will be revealed.
Ro 2:8 -
but for those who are factious and do not obey the truth, but obey wickedness, there will be wrath and fury.
Ro 3:5 -
But if our wickedness serves to show the justice of God, what shall we say? That God is unjust to inflict wrath on us?
Ro 9:22 -
What if God, desiring to show his wrath and to make known his power, has endured with much patience the vessels of wrath made for destruction,
Ro 13:4 -
for he is God’s servant for your good. But if you do wrong, be afraid, for he does not bear the sword in vain; he is the servant of God to execute his wrath on the wrongdoer.
Ro 13:5 -
Therefore one must be subject, not only to avoid God’s wrath but also for the sake of conscience.
Eph 2:3 -
Among these we all once lived in the passions of our flesh, following the desires of body and mind, and so we were by nature children of wrath, like the rest of mankind.
Eph 5:6 -
Let no one deceive you with empty words, for it is because of these things that the wrath of God comes upon the sons of disobedience.
Col 3:6 -
On account of these the wrath of God is coming.
Col 3:8 -
But now put them all away: anger, wrath, malice, slander, and foul talk from your mouth.
Another dispensationalist error is the notion that the Book of Revelation “deals primarily with the time period of the Tribulation, is a prophetic message of how God will pour out His wrath upon the earth during the Tribulation.” In reality, only the last two chapters deal explicitly with the Second Coming. The rest of the book, most scholars say, deals with events in the first century.
