And it came to pass, when they were come, that He looked on Eliab, and said, surely the Lord’s anointed is before Him.

But the Lord said unto Samuel,  Look not on his countenance, or on the height of his stature; because I have refused him: for the Lord seeth not as man seeth; for man looketh on the outward appearance, but the Lord looketh on the heart.

1 Samuel 16:6-7 KJV

The Lord sent Samuel to anoint the king; God had already chosen who would be the king and Samuel thought he knew. God points out the trouble with how man chooses people for certain things: Man looks at the outer appearance and God looks at the heart. It’s natural to figure that the more powerful looking person would be better for the job, but that’s not necessarily the case. I’ve seen strong looking people who couldn’t do any more than a smaller person. I’ve seen people who talked a good game, and used really big words who really didn’t know much at all. But you take a man whose heart is committed to serve the Lord, and there’s nothing on this earth he can’t do. When a man’s heart is set on God, that man is empowered by God. That’s the kind of individual you want to appoint to be over things. This is the leader you want leading others. Not to say this individual won’t make mistakes, because they will. We are human. But just like David, there are people who, on the outside may look like they can’t do what needs to be done. Pray and ask God to help you discern in these kind of decisions. Don’t just judge by what you see on the outside. What matters most is the condition of an individual’s heart.
