Youngest son

 Was Goliath David's neighbour 

They could see across the valley of Elah

What God commands He also hands 

His power to this ruddy, young fella 

Some things we can't question, take them as read

There's a chasm tween the old and the new 

Jesus, our Saviour, commands our behaviour 

Entire law is fulfilled with His view

Saul's a head taller, David's brothers were too 

They were warriors and older for a start 

Folks see appearance, God sees adherence 

He and He only sees heart.

1 Samuel 16:6-12 (NIV)

6 When they arrived, Samuel saw Eliab and thought, “Surely the LORD’s anointed stands here before the LORD.”

7 But the LORD said to Samuel, “Do not consider his appearance or his height, for I have rejected him. The LORD does not look at the things people look at. People look at the outward appearance, but the LORD looks at the heart.”

8 Then Jesse called Abinadab and had him pass in front of Samuel. But Samuel said, “The LORD has not chosen this one either.” 9 Jesse then had Shammah pass by, but Samuel said, “Nor has the LORD chosen this one.” 10 Jesse had seven of his sons pass before Samuel, but Samuel said to him, “The LORD has not chosen these.” 11 So he asked Jesse, “Are these all the sons you have?”

“There is still the youngest,” Jesse answered. “He is tending the sheep.”

Samuel said, “Send for him; we will not sit down until he arrives.”

12 So he sent for him and had him brought in. He was glowing with health and had a fine appearance and handsome features.

Then the LORD said, “Rise and anoint him; this is the one.”

Galatians 5:14 (NIV)

14 For the entire law is fulfilled in keeping this one command: “Love your neighbor as yourself.”
