It's easy in our day of age, to forget about Martin. Our generation seems to take racial equality for granted. It doesn't seem like such a big deal now that everything has changed. It's pretty easy to assume that he was popular and everyone liked him and everyone totally agreed with what he said.
Those things however were not true. It's not often you'll find someone who doesn't care about what the world thinks and is willing to take a stand for what they believe in. Martin found it hard to find many people that agreed with him. He was arrested numerous times, people threatened to blow up his house, riots often stormed outside his house, and he was eventually assassinated. He was the opposite of popular. He did all that just to do what was right.
This kind of reminds me of a man named Paul (a.k.a. Saul). God gave him a second chance and he started spreading the gospel. He too stopped caring what other people thought. He was beaten and tortured and thrown in Jail for doing what's right even though everyone else was else was doing wrong.
Right before Martin's death, Martin started working on things like poverty and arguments between countries. He never really got a chance to finish the job. Right now the poverty level is extremely high and even at this moment people all over the world are fighting just because they're from different backgrounds. I guess that's kind of where we need to pick up.
