His. These insolent mockers do not even wish to pronounce the worshipful name of the Lord Jesus Christ. They refer to Him contemptuously with a pronoun.
For since, and so forth. From the beginning, everything has gone according to its usual order. Nothing like what is spoken of as the future coming will occur, just as nothing like it has occurred. Such is the thought of these mockers.
Since the fathers began to fall asleep. Fathers means ancestors in the general sense, or the whole human race, from the time people began on earth. From the beginning of creation is an even stronger expression. Not only since people began to die, but from the very beginning of creation, everything has gone according to its established order in heaven and on earth, in all its parts.
All things remain, or abide, as they were. This means in essence and as a whole, apart, of course, from ordinary particular changes in nature and life. Such changes have no essential significance for the standing of the basic laws of the world.
According to the meaning of the mockers in question, the basic laws of the world act and will always act as they have acted. Therefore, they say, there will not and cannot be any special coming of Christ. The world will always be as it has been.
"Those who live passionately according to their own lusts shamelessly attack believers and mock them. They do this because the event does not follow the prophecy of the Lord's coming at once. Instead, an interval has been allowed for the salvation of those written in the book of the saved" (Theophylact).
