The practical subjectivity of reality

It could be that the title of this blog is not exactly accurate, so I'll explain a little. Everyone has had a lifetime of experiences and education that has formed who they are and how they think about things.  Following from this, everyone is different.  This means that the way people see reality and interpret common and uncommon events differ.  This is not to say that reality is malleable but that people understand reality differently.
I believe that one very important thing to glean from this observation is the fact that we cannot judge another person on the presumption that we understand what they are doing and why.  Our thinking will be different from theirs, the world that formed their thinking will have been different from ours and their rationale for why they do what they do will be different from ours.
The important thing here is love.  When we love someone, we do not judge them, we do not assume that we know better or would respond better than they in a situation, and we don't look down upon another for the situation they are in.  We must, as part of the body of Christ, love unconditionally and pray for all men.
As Jesus said, "By this everyone will know that you are my disciples, if you love one another."- John 13:35
