It's so important to listen for God's heart and mind. Not many stop to hear his will, nor care to.
Here God is speaking to Eli about his uncaring attitude as high priest. His two sons are sleeping with women around the tabernacle and bullying the people who come to sacrifice.
Prayer: God, I would like to have a heart like Samuel's that you describe as doing what is in your heart and mind. He was in tune with and in step with your heart, mind, and spirit.
God wants to raise up people like Samuel that will raise up King David's and judge fairly in the land.
