Giving to the Homeless

I was reading in Mosiah 4, specifically vs.17-26. I have never felt like it was wrong for me to not give handouts, food, or rides to homeless people for a number of reasons. First, I pay my tithing and a generous fast offering so I've done my duty, right? Second, the world is a much less safe place than it has been in the past and I don't feel like it would be safe to take a hitchhiking stranger somewhere in my car. Third, there are supposed to be government programs that should take care of these people (whether they are effective or not is a different problem). So the question is this-Is it wrong for me to continue in this way, or should I give money/food/rides to those homeless individuals I see?

Appearances After Resurrection

My mom and I were having this discussion today: Are we going to look like ourselves after we are Resurrected, only glorified? Or are we going to be able to change some things about how we look?

Angels

I personally don't believe that we have "guardian angels" assigned to us. What do you think?

Abraham 4:4

"And they (the Gods) comprehended the light, for it was bright; and they divided the light, or caused it to be divided, from the darkness."

I think this verse (and the rest of the chapter, actually) is very interesting in that it refers to "Gods" not "God" creating the Earth, etc. This post was more of a thought than a question. What do you think about this? I had always been under the impression that Christ created the Earth.

Will there be people of different race in heaven?

I have often wondered if there will be people of different race in heaven. My first initial thought was "yes, of course". But then I started thinking about how Joseph Smith said that they were brilliantly white, etc. and how one of the apostles said that the "official" picture of Christ did in fact look like him (and thus Heavenly Father looks like that). So, if we are created in the image of God, and he looks like that picture, then can there be race in heaven? The other thought is that darker skin is the sign of the curse that came upon the posterity of Cain for his sin (the actual curse was the removal of the priesthood from his line), so could there be dark skin because that was essentially a deformation?
