The Only Reason for Boasting

So I went to a Cubs game last night down in Cincinnati. I don't know who is familiar with the electronic races that happen on the jumbotron TVs, but I'll try and explain them.
For this particular race there were three race cars on the TV, and then they showed the three people who represented each one of the cars. Person #1 would be paired up with car #1. Person #2 with car #2, and so on.
The cars drove from start to finish, and whatever car number won then the person who was paired with that number won a prize. It would show the person who's car won, and they were cheering as if they played a role in the race. If you didn't catch on earlier, the race is totally done by electronics and is totally random. I was probably the only person in the whole stadium that made a biblical analogy out of what I just saw.
Basically the winner is the one who is justified. What did he do to be justified? He didn't do anything. He sat and watched the car do everything for him. Then he started cheering like he was the one who was driving the car and had won the race. Are you starting to see a biblical connection?
We can only be justified because of what Christ has done for us, but most of the time we like to boast and act like we were the one's who have obtained our own salvation. That kid can and should only boast in the work of his race car, just as we can and should only boast in Jesus Christ and the work he did for us. He lived a perfect/sinless life, he atoned fully for our sins on the cross, and he proved his divinity by fulfilling the Scriptures and rising from the dead on the third day, and he is now seated at the right hand of God interceding for us constantly.
This analogy isn't anything special, but it does show us a picture of how we should view pride and our own glory. From what I just said, we shouldn't have any pride, because what have we done in order that we should benefit? We need to stop trying to justify our pride, and give it to God, the only one who has something to boast about. And for us, we can only boast in what God has done as well, because in him is where our benefit is found.
