Things I'm learning from David's life

I have been going through 1 and 2 Samuel lately and today I finished 2 Samuel.  Things I am learning from David:

God is honoured when we honour His choice of leadership
Even though David was chosen to be the next king, David showed respect and dignity to Saul on a continual basis, even when Saul was against God and was trying to take David's life. 

God is honoured when we worship Him from our heart and not based on other people's expectations
David danced with only a linen cloth in front of the Lord in front of all of the people.  He was not hindered by other people's expectations on how he should act, not even when his wife opposed his actions. 

There is always consequences to sin and disobedience to God
Although David was a man after God's own heart, he did sin and the consequences were serious.  From death in his family to pestilence to the whole country, David's action affected others.
