If we know the rapture's in 2023, what more do we need to know?
I would say you need to know Matthew 25
However, these verses in Matthew 24 are a good summary
45 Who then is the faithful and wise servant, whom his lord hath set over his household, to give them their food in due season? 46 Blessed is that servant, whom his lord when he cometh shall find so doing.
This covers the next three parables. You see what the faithful servant is, then you see the wise virgins and finally you see those entrusted with the talents who are about their Lord's business doing what they are supposed to be doing when He returns. In all of this you see that they are watching and paying attention to the signs and prophecies, that is implied in the term "in due season". How would you know what the season is if you are not paying attention to the signs? According to the context the sprouting of the Fig tree tells you that summer is near, an example of knowing the seasons.
47 Verily I say unto you, that he will set him over all that he hath. 48 But if that evil servant shall say in his heart, My lord tarrieth; 49 and shall begin to beat his fellow-servants, and shall eat and drink with the drunken; 50 the lord of that servant shall come in a day when he expecteth not, and in an hour when he knoweth not,
Hold on a second! Aren't there many out there telling us that all believers do not know when the Lord is coming? How can this be a warning if when the Lord comes no one expects it and no one knows it? So then be warned. The Christians (servants of the Lord) who are telling you that these prophets are wrong, the Lord is not coming, and then they beat up the prophets, saying Dana Coverstone's dream showed the US being like the Great Depression, that didn't happen. These "Christians" are saying this because they eat and drink with the drunken. They don't want the Lord to return. Paul talked about a crown for all those who "love the Lord's appearing". These ones don't love the Lord's appearing.
51 and shall cut him asunder, and appoint his portion with the hypocrites: there shall be the weeping and the gnashing of teeth.
The outer darkness, the ones left behind after the rapture.
