What's My Purpose?

Mark 3:13-19

Jesus went up the mountain and summoned those whom he wanted 
and they came to him.
He appointed Twelve, whom he also named Apostles,
that they might be with him
and he might send them forth to preach 
and to have authority to drive out demons:
He appointed the Twelve:
Simon, whom he named Peter; 
James, son of Zebedee, 
and John the brother of James, whom he named Boanerges, 
that is, sons of thunder;
Andrew, Philip, Bartholomew,
Matthew, Thomas, James the son of Alphaeus; 
Thaddeus, Simon the Cananean,
and Judas Iscariot who betrayed him.

I read this here and can't help but think that we are all chosen in some way. How am I chosen? How are you chosen? I have been on a journey for some time to try and figure out my place in this world. What does God want me to do. I know that there are many things that he wants me to do. He wants me to love my brothers and sisters in humanity. God wants me to love him and have a relationship with him and much more, but what is my mission? This is something that I have been praying on and it is slowly coming into focus. It wasn't till yesterday that while studying during a day of fasting that things became a bit more clear. I just hope that I see what Jesus wants and that I execute as well as the apostles did. I don't want to let Jesus down. 

Jesus, 

I know that we all have a place in this world. Please help me find mine. I know that I am going to make some wrong turns here and there so please be patient. Smack me around if you have to. I can be rather thick sometimes. You have done so much for me. I can never repay you. I love you.

In Jesus Christ's name I pray,
Amen
