Afterlife

How we should beheave with the wicked people who are intoxicated by evil inclination?

do we get to meet our dead relatives again after we die?

Was the idea of gehinnom built off of God's word or is it entirely speculation? How much detail about what happens after death was explicitly within God's word?

If I pass away at the age of 30 (G-d forbid), and I have a child of 5 years old. Then he grows up to be 65. Then, the resurrection of the dead happens. Will I come back as a 30 year old, while my child is 65?

What is the source for having an aufruf on a Thursday, if one wants to make it then? Saw this: "In the Ashkenazic Jewish community the aufruf ceremony is typically held on the Shabbat before the wedding; but it can also be held on a Monday or Thursday." The family finds it hard to make the aufruf on Saturday, since the wedding is on the next day - Sunday. Thanking you in advance, (name withheld in Rabbi's reply)

Is there a devil, or an enemy of God?

Gmar chasima tova! All our tzadikim, Avraham, Yitzchok, Yaakov, that are in olam Habah right next to the kisay hakavod. What are they lacking that won’t be fulfilled till mashiach comes and they get tichias hameisim- what is so great about techies hameisim as opposed to olam habah?
