The Lord looks at our heart. Many people try to appear godly by putting on a beautiful display, dressing to perfection, and speaking empty words to cover the truth.
Saul didn’t follow the instructions of the Lord when he went to war, and the Lord regretted making him king. He sent Samuel to anoint a new king from the family of Jesse, a Bethlehemite. When he saw Eliab, he was sure that this son was the one the Lord wanted, but God had other plans, and told Samuel not to look at his height or stature because he had rejected him, and told him that he looks at the heart. This should cause many to tremble; you can look as spiffy as you want, but God can see the hate hidden in your heart.
As each of us try to keep a nasty virus at bay by staying clean and washing our hands continuously, if we don’t have a clean heart, we may already be dead. Pray that the Lord brings to your attention any areas of your heart that need refining, and allow him to do a work in you. I don’t know about you, but I would never want to be passed up for promotion like Eliab, and his brothers, because of an unclean heart.
When they came, he looked on Eliab and thought, “Surely the LORD's anointed is before him.” But the LORD said to Samuel, “Do not look on his appearance or on the height of his stature, because I have rejected him. For the LORD sees not as man sees: man looks on the outward appearance, but the LORD looks on the heart.” 1 Samuel 16:6-7
