In the last days
The term "last days" is derived from the Greek "eschatos," which refers to the final period of time. This phrase is often associated with eschatological themes throughout the New Testament, indicating the period between Christ's first and second coming. Historically, the early Christians believed they were living in these "last days," a time characterized by both the fulfillment of God's promises and the intensification of spiritual warfare. This understanding calls believers to live with a sense of urgency and readiness, recognizing that the culmination of God's redemptive plan is at hand.

terrible times
The Greek word for "terrible" is "chalepos," which can also be translated as "difficult," "dangerous," or "fierce." This term conveys the severity and intensity of the challenges that will arise. Historically, the early church faced persecution, false teachings, and moral decay, which align with this description. The "times" (Greek "kairos") refers to specific, opportune moments rather than a continuous period, suggesting that these challenges will come in waves or seasons. This serves as a warning to be vigilant and steadfast in faith.

will come
The phrase "will come" is translated from the Greek "enistēmi," meaning to be present or to stand upon. This indicates certainty and inevitability. Paul is not suggesting a possibility but a definite occurrence. For the early church, this was a prophetic insight into the trials they would face, and for contemporary believers, it serves as a reminder that spiritual and moral challenges are an expected part of the Christian journey. This certainty calls for preparedness and reliance on God's strength to endure and overcome.

(1) This know also.--Better rendered, But know this. The Apostle had warned Timothy (2Timothy 2:3-13) not to allow fear of oncoming peril and trouble to paralyse his efforts in the Master's cause, for the Lord's true servant should never lose heart, and then had proceeded (2Timothy 2:14-26) to detail how these efforts of his were to be directed, showing him how his teaching should stand in contrast with that of the false teachers. St. Paul now (2Timothy 3:1), having told him that although there was no reason to fear, yet warns him that grave dangers to the Church would surely arise, and that God's servants, like Timothy, must be prepared to combat.

In the last days.--The majority of commentators have referred "the last days" here spoken of to the period immediately preceding the second coming of the Lord--a day and an hour somewhere in the future but hidden, not merely from all men, but from the angels, and even from the Son (Mark 13:32).

It seems, however, more in accordance with such passages as 1John 2:18 : "Little children, it is the last time"--where the present, and not an uncertain future is alluded to--to understand "the last days "as that period, probably of very long duration, extending from the days of the first coming of Messiah--in which time St. Paul lived--to the second coming of Christ in judgment. The Jewish Rabbis of the days of St. Paul were in the habit of speaking of two great periods of the world's history--"this age," and "the age to come." The former of these, "this age," including all periods up to Messiah's advent; the latter, "the age to come," including all periods subsequent to the appearance of Messiah. We find the same idea embodied later in the Talmud (treatise "Sanhedrim") 6,000 years are mentioned as the duration of the world, 2,000 years, waste or chaos, 2,000 years under the law, 2,000 years the days of Messiah." This last period, "the days of Messiah," are often alluded to by the Hebrew prophets under the expression, "in the last days"--literally, in the end of days. (See Isaiah 2:2; Hosea 3:5; Micah 4:1.) The words of 2Timothy 3:5, "from such turn away," would require certainly a strained interpretation if we are to suppose that the "last days" referred to a time immediately preceding the end, or, in other words, the last period of the Christian era. The sad catalogue of vices is, alas, one with which all ages of the Church of Christ has been too well acquainted. The Christian teacher has no need to look forward to a future time of deeper iniquity, when in the Church of the living God will be found those who will deserve the dreary titles of this passage. The Church of his own age will supply him with examples of many such, for "In a great house . . . are there not only vessels of gold and silver, but also of wood, and earth, and some to honour and some to dishonour." . . .
