Jonathan, by default, was in line to be the next King of Israel. He served God faithfully. 
Within a short period of time that responsibility was taken from him and given to another man. Jonathan still served God faithfully. 
In my opinion, Jonathan is one of the most humble people in the Word. No matter how God wanted to use him he was willing. He wasn’t after fame, recognition or what he felt he deserved. He was just found chasing after God’s will for his life.
