In that day, is a general reference to a time when these events will take place. With respect to individuals, it refers to the time when the individual repents and changes their way. However, Isaiah uses the term every man, or everyone, which is a reference to a society-wide change. And of course, when referring to the mass repentance of the Jewish nation, then the phrase, in that day, refers to the end times of human history, or the final months and days immediately preceding the second advent of Christ.
The tribulation, is the last segment of time, immediately prior to the second advent of Christ. The tribulation will last seven years. It begins immediately after the rapture of believers from our dispensation, and continues for seven years, and ends with the second advent of Christ.
During those seven years, the most horrible things in all of human history will occur. And during the last months and years of the tribulation, the city of Jerusalem will be surrounded and assaulted over and over again, but somehow, by the grace of God, it will survive until the very end.
During that time of intense pressure, the Jewish people within that city will come to their senses, will repent and turn to Christ, and give up all of their old ways and beliefs, as it were, herein referred to as idols of gold and silver.
Gold and silver are common ingredients for making idols, but they are also references to secular priorities that people have set for themselves.
And the phrase, made with your own hands, clearly describes that all of the sinful paths that people have taken, were due to their own decisions, and of their own making.
Regardless of the type or make up of the idols, or distractions, or lusts, or attitudes, that people formed for themselves, in lieu of Bible doctrine, those choices were made against God, and against Christ, and against truth.
And as the entire period of the tribulation will portray, the human race, as a whole, will bring itself into the tribulation, because of all of the collectively wrong choices that have, and will, be made throughout history.
And specifically, the Jewish race, which has historically and stubbornly rejected Christ, will not repent until the extreme state of world ending events, take place. That is the quintessence of stubbornness and arrogance.
And of course, this is not restricted to the Jewish race, but is a worldwide attitude of being negative toward Christ, that will bring the entire planet into the tribulation, and to the self-destructive near extinction of humanity.
Sometimes, it takes tremendous extremes, before people actually see the truth, and change.
