Young Samuel grew up in the Tabernacle, under the care of Eli the priest. You can read the story of Samuel’s childhood in 1 Samuel 1 – 3.
1 Samuel 3:10 (NIRV)
The Lord came and stood there. He called out, just as he had done the other times. He said, “Samuel! Samuel!”
Then Samuel replied, “Speak. I’m listening.”
Three words. No fancy phrases. No list of prayer requests. Just a simple statement:
I’m listening, Lord.
