'On that Day' in the Bible

I tell you, the people of Sodom will be shown more leniency on that day [i.e., the day of judgment] than that town will receive.

On that day, the person who is on a housetop [Note: This was a flat area where people retired for rest, prayer, etc., with its stairway on the outside], whose belongings are [still] in his house, is not to go down and [attempt to] take any of them away. And the person who is in a field [i.e., doing farm work], also is not to return [to his house].

But you should be alert at all times, offering earnest prayers, so that you will be strong enough to escape all these things that will happen, and to appear [acceptable] in front of the Son of man [on that day]."

So, when it was evening on that day, [which was] the first day of the week [i.e., Sunday] and the doors [of someone's house], where the disciples were gathered, were closed [i.e., probably locked] for fear of the Jewish authorities, Jesus came and stood among them. [Note: Probably Jesus passed through the closed door miraculously]. He said to them, "May there be peace in your hearts."

Then those who responded [by faith] to the words [spoken by Peter and the apostles] were immersed, and about three thousand persons were added to them [i.e., the apostles] on that day.

On that day Jesus will return to be honored by His saints [i.e., God's holy people] and to be marveled at [i.e., in reverence] by all those who had believed [in Him]. [This will happen] because you have believed our testimony to you [about Christ].

May the Lord grant that he will find mercy on that day [i.e., the day of judgment]. And you know very well the many things he did to serve [me while I was] at Ephesus.

So, now there is a crown of righteousness reserved for me, which the Lord, who is a just Judge, will award me on that day [i.e., the judgment day], and not to me only, but also to everyone who has loved [the prospect of] His appearing.
