Maybe it was a reference to 2 Tim 2:15.
14 Remind them of these things, charging them before the Lord not to strive about words to no profit, to the ruin of the hearers. 15 Be diligent to present yourself approved to God, a worker who does not need to be ashamed, rightly dividing the word of truth. 16 But shun profane and idle babblings, for they will increase to more ungodliness. 17 And their message will spread like cancer.
2 Timothy 2:14-17 NKJV (emphasis added so you can find it)
... not "gibberish", not "dispensationalist nonsense"
And, in fact - the full context of the referenced phrase reveals several other timely and pertinent truths.
(File under things that make you say, "Hmmm...")
2 Tim 2:15 = [15] Carefully study to present thyself approved unto God, a workman that needeth not to be ashamed, rightly handling the word of truth.
The WORD of God is Jesus Christ, the Bible is a collection of 73 God inspired/God-breathed books
Dispensationalism is biblically false
According to Hebrews 1:1-2, "God, after He spoke long ago to the fathers in the prophets in many portions and in many ways, in these last days has spoken to us in His Son, whom He appointed heir of all things, through whom also He made the world."
At Pentecost, Peter preached that "the last days" had arrived, in fulfillment of the words of the prophet Joel: "For these men are not drunk, as you suppose, for it is only the third hour of the day; but this is what was spoken of through the prophet Joel: 'And it shall be in the last days,' God says, that I will pour forth my spirit on all mankind . . ." (Acts 2:15-17; cf. Joel 2:28-32).
"The last days" or "the end times," properly understood, refers to the time of the New Covenant, the gathering together of God's people in the community of Christians called the Church - The Holy Spirit, the "soul of the Church," has been -- and is being -- poured out, because of the redemptive work of Jesus Christ
The Kingdom of heaven on earth is already inaugurated with Christ's resurrection - refer acts 17
Acts 17: 6 [a]When they could not find them, they dragged Jason and some of the brothers before the city magistrates, shouting, “These people who have been creating a disturbance all over the world have now come here, 7 and Jason has welcomed them. They all act in opposition to the decrees of Caesar and claim instead that there is another king, Jesus.”
The Kingdom was at hand, i.e. was near when Christ preached on earth. The Kingdom is here, and has been inaugurated since 33 AD - that's what the Apostles were preaching, that is the Good News, the Gospel, the ONE Gospel that the disciples were preaching as seen in Acts 17
