Saul, the new king, fails to follow the Lord.  Observe:

• Heart for God – Saul offers a sacrifice that is not his to make, and so disobeys God. Samuel tells Saul that his kingdom will not continue, for God is seeking a man after his own heart.  In other words, Saul’s disobedience reveals his heart – and it is not after God.  Where is your heart?  Do your actions reveal a heart for God or not?
• Obedience – As Saul disobeyed God in chapter 13, so he does it again in chapter 15 – apparently following the people instead of God. Are you following God or the crowd around you?  In what ways are you tempted to follow those around you?
