Lead to obey (2)
"Saul told his son Jonathan and all his officials that he planned to kill David. But Jonathan was very fond of David, and so he said to him, “My father is trying to kill you. Please be careful tomorrow morning; hide in some secret place and stay there. I will go and stand by my father in the field where you are hiding, and I will speak to him about you. If I find out anything, I will let you know.”
Jonathan praised David to Saul and said, “Sir, don't do wrong to your servant David. He has never done you any wrong; on the contrary, everything he has done has been a great help to you. He risked his life when he killed Goliath, and the LORD won a great victory for Israel. When you saw it, you were glad. Why, then, do you now want to do wrong to an innocent man and kill David for no reason at all?”"
~ 1 Samuel 19.1-5 GNB
How many crown prince do you know who helped someone else be the next king? Essentially, that was what Jonathan did. By world standard, he was the heir to the throne, but he went by the LORD's standard instead. Jonathan chose to do the right thing.
A leader's role is to lead people to obey the LORD.
