I think I'd be ok to say that we all live pretty selfish lives. We think about ourselves before almost anything else. This isn't necessarily bad, it's just human nature. It is bad though when we don't let ourselves get past our first initial self centered thoughts.
There have been so many times where I've been in situations and all I can think about is me. The situation I keep finding myself doing this is when I am walking by the homeless. I try not to make eye contact with them. I walk briskly by and sometimes even ignore them when they try and make conversation. I know, I know, I'm a jerk. But I've now made it a point to just embrace the opportunity to show love to anyone at anytime. What could I possibly have that is more important than spreading Christ's love?
The big idea here is that we make way too many compromises. Let's look at this in a big picture way. Throughout life we make excuses when situations come our way. We start to think certain things are more important than the Kingdom. We are too old or young to live out the desires God has placed in our hearts, the list goes on, but God has given us specific gifts and tasks to do and they bring glory to Him.
It can be hard to stay focused on the work that God has given us. But that is the whole point to our existence. I've noticed that It's always pretty easy for young people to have big goals and dreams that seem impossible, but are willing to work hard and not let the odds mean anything to them. And I've seen and experienced myself, the reaction older people have to young dreamers. It's a mixture of excitement and jerkiness. To me it shows that maybe they had dreams that they compromised so they could do "life", when in reality compromising your dreams takes all the life out of living. This isn't a bash on the older generations, it's more of a callback to your dreams. It can be hard to look back at your life and realize you didn't really do what you wanted. It can be paralyzing, but it doesn’t have to be.
If it's hard for young people to find themselves and what they love, and express that with their life, it has to be a million times harder for older people who compromised themselves for an "ordinary" life. It's never too late to make a change though. We have to think selflessly and remember that the dreams God has put in us are our jobs, the work that will bring Him glory.
